Item 3.01. Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

        The disclosures under Item 8.01 - Other Matters below are incorporated by reference herein.

Item 8.01. Other Matters.

        This Form 8-K updates disclosures previously made by United States Cellular Corporation ("U.S. Cellular") on Form 8-K dated November 6, November 13, November 15, November 22 and December 8, 2006, January 12 and January 22, 2007 relating to the restatement of certain financial statements and delayed filing of its Quarterly Report on Form 10-Q ("Form 10-Q") for the period ended September 30, 2006.

        On November 6, 2006, U.S. Cellular disclosed that it will restate its financial results for each of the three years in the period ended December 31, 2005, including quarterly information for 2005 and 2004, and certain selected financial data for 2002. U.S. Cellular also disclosed that it will restate its Form 10-Q for the periods ended March 31, 2006 and June 30, 2006 (collectively, "the restatements").

        As a result of the restatements, U.S. Cellular also disclosed that it would delay the filing with the Securities and Exchange Commission ("SEC") of its Form 10-Q for the period ended September 30, 2006.

        As previously disclosed, the restatements and delayed filings have resulted in defaults under a revolving credit agreement between U.S. Cellular and certain lenders and under certain forward contracts between a subsidiary of U.S. Cellular and a counterparty and in non-compliance with listing standards of the American Stock Exchange ("AMEX").

        U.S. Cellular previously received waivers under the revolving credit agreement and forward contracts, provided that U.S. Cellular files the restatements and Form 10-Q for the period ended September 30, 2006 by February 12, 2007. U.S. Cellular requested and received extensions of such waivers, provided that U.S. Cellular files the restatements and Form 10-Q for the period ended September 30, 2006 by March 14, 2007.

        It is necessary for U.S. Cellular to complete and file the restatements and its Form 10-Q for the period ended September 30, 2006 before it can complete and file its Form 10-K for the year ended December 31, 2006. Such Form 10-K is due on March 1, 2007, but such deadline can be effectively extended to March 16, 2007 by filing Form 12b-25 with the SEC on or prior to March 2, 2007. Although a Form 12b-25 will be filed by U.S. Cellular on or prior to March 2, 2007, U.S. Cellular may not be able to complete the Form 10-K for the year ended December 31, 2006 by the extended due date of March 16, 2007. The late filing of the Form 10-K for the year ended December 31, 2006 will result in defaults under the revolving credit agreement and forward contracts. Accordingly, U.S. Cellular received waivers pursuant to which such defaults would be waived, provided that U.S. Cellular files its Form 10-K for the year ended December 31, 2006 by the earlier of (a) 60 days after the filing of the Form 10-Q for the period ended September 30, 2006 or (b) May 14, 2007.

        It is necessary for U.S. Cellular to complete and file the restatements, its Form 10-Q for the period ended September 30, 2006 and its Form 10-K for the year ended December 31, 2006 before it can complete and file its Form 10-Q for the quarter ending March 31, 2007. Such Form 10-Q is due on May 10, 2007, but such deadline can be effectively extended to May 15, 2007 by filing a Form 12b-25 with the SEC on or prior to May 11, 2007. Although a Form 12b-25 will be filed with the SEC on or prior to May 11, 2007, U.S. Cellular may not be able to complete the Form 10-Q for the quarter ending March 31, 2007 by the extended due date of May 15, 2007.

The late filing of the Form 10-Q for the quarter ending March 31, 2007 would result in defaults under the U.S. Cellular revolving credit agreement and forward contracts. Accordingly, U.S. Cellular received waivers pursuant to which such defaults would be waived, provided that U.S. Cellular files its Form 10-Q for the quarter ending March 31, 2007 by the later of (a) May 15, 2007 or (b) the earlier of (i) 45 days after the filing of the Form 10-K for the year ended December 31, 2006 or (ii) June 28, 2007.

        U.S. Cellular previously received an extension to regain compliance with the AMEX listing standards until February 12, 2007. On February 12, 2007, the AMEX granted U.S. Cellular an extension until March 14, 2007 to regain compliance with AMEX listing standards. U.S. Cellular will be in compliance with such listing standards when it files the restatements and its Form 10-Q for the period ending September 30, 2006. However, U.S. Cellular will cease to be in compliance with such standards if it does not file its Form 10-K for the year ended December 31, 2006 by the extended due date of March 16, 2007 or its Form 10-Q for the period ending March 31, 2007 by the extended due date of May 15, 2007. In such event, U.S. Cellular will seek extensions from the AMEX at such time.

        On February 12, 2007, U.S. Cellular and its parent company, Telephone and Data Systems, Inc., issued a joint press release relating to the foregoing, which is attached hereto as Exhibit 99.1 and incorporated by reference herein.

FOR RELEASE: IMMEDIATE

TDS AND U.S. CELLULAR RECEIVE FURTHER EXTENSIONS FROM AMEX AND LENDERS
Companies require additional time to complete restatement of prior period results

CHICAGO - Feb. 12, 2007 - Telephone and Data Systems, Inc. [AMEX:TDS, TDS.S] and United States Cellular Corporation [AMEX:USM] today announced that the American Stock Exchange (AMEX) granted both companies an extension until March 14, 2007 to regain compliance with AMEX listing standards resulting from delayed filing with the Securities and Exchange Commission (SEC) of their Forms 10-Q for the quarter ended Sept. 30, 2006. Previously, the AMEX had notified both companies that it had accepted their plans to regain compliance and had granted both companies an extension until Feb. 12, 2007 to make these delayed filings. TDS and U.S. Cellular continue to be noncompliant with the listing standards of the AMEX and their listing is being continued pursuant to the additional extension of time to March 14, 2007 to regain compliance.

TDS and U.S. Cellular require additional time to complete the restatement of prior period results announced on Nov. 6, 2006. As a result, the companies may not be able to complete and file their Forms 10-K for the year ended Dec. 31, 2006 and their Forms 10-Q for the quarter ended March 31, 2007 on time. TDS and U.S. Cellular are working diligently to complete and file these additional forms accurately and as timely as possible. If necessary, TDS and U.S. Cellular will seek extensions from the AMEX for filing their Forms 10-K for the year ended Dec. 31, 2006 and their Forms 10-Q for the quarter ended March 31, 2007 after these documents are considered late.

In addition, both companies have received extended waivers from their lenders under credit agreements and from counterparties under certain forward contracts provided that that they file their Forms 10-Q for the quarter ended Sept. 30, 2006 by March 14, 2007, their Forms 10-K for the year ended Dec. 31, 2006 within 60 days of filing the Forms 10-Q for the quarter ended Sept. 30, 2006, and their Forms 10-Q for the quarter ended March 31, 2007 within 45 days of filing the 2006 Forms 10-K. Waivers of defaults were previously extended, on the condition that the companies file their Forms 10-Q for the quarter ended Sept. 30, 2006 on or before the extended due date of Feb.12, 2007.

On Nov. 6, 2006, the companies announced that they would restate financial results for each of the years ended Dec. 31, 2002 - 2005, quarterly information for 2004 and 2005, and the first and second quarters of 2006. The restatement was required primarily to correct the accounting for prepaid forward contracts under Statement of Financial Accounting Standards (SFAS) No. 133, Accounting for Derivative Instruments and Hedging Activities. The companies have also included adjustments in the restatement for items representing out-of-period adjustments and corrections of errors, some of which were identified during 2006.

Exhibit 99.2

PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995
SAFE HARBOR CAUTIONARY STATEMENT

This Form 8-K and/or press release attached to this Form 8-K contain statements that are not based on historical fact and represent forward-looking statements, as this term is defined in the Private Securities Litigation Reform Act of 1995. All statements, other than statements of historical facts, that address activities, events or developments that U.S. Cellular intends, expects, projects, believes or anticipates will or may occur in the future are forward-looking statements. The words "believes," "anticipates," "estimates," "expects," "plans," "intends" and similar expressions are intended to identify these forward-looking statements, but are not the exclusive means of identifying them. Such forward-looking statements involve known and unknown risks, uncertainties and other factors that may cause actual results, events or developments to be significantly different from any future results, events or developments expressed or implied by such forward-looking statements. Such risks, uncertainties and other factors include those set forth below, as more fully discussed under "Risk Factors" in U.S. Cellular's Form 10-K for the year ended December 31, 2005. However, such factors are not necessarily all of the important factors that could cause actual results, performance or achievements to differ materially from those expressed in, or implied by, the forward-looking statements contained in this document. Other unknown or unpredictable factors also could have material adverse effects on future results, performance or achievements. U.S. Cellular undertakes no obligation to update publicly any forward-looking statements whether as a result of new information, future events or otherwise. You should carefully consider the Risk Factors in U.S. Cellular's Form 10-K for the year ended December 31, 2005, the following factors and other information contained in, or incorporated by reference into, this Form 8-K and/or press release attached to this Form 8-K to understand the material risks relating to U.S. Cellular's business.

• Intense competition in the markets in which U.S. Cellular operates could adversely affect U.S. Cellular's revenues or increase its costs to compete.
  
  
• Consolidation in the telecommunications industry could adversely affect U.S. Cellular's revenues and increase its costs of doing business.
  
  
• Advances or changes in telecommunications technology, such as Voice over Internet Protocol or WiMAX, could render certain technologies used by U.S. Cellular obsolete, could reduce U.S. Cellular's revenues or could increase its costs of doing business.
  
  
• Changes in the regulatory environment or a failure by U.S. Cellular to timely or fully comply with any regulatory requirements could adversely affect U.S. Cellular's financial condition, results of operations or ability to do business.
  
  
• Changes in U.S. Cellular's enterprise value, changes in the supply or demand of the market for wireless licenses, adverse developments in the business or the industry in which U.S. Cellular is involved and/or other factors could require U.S. Cellular to recognize impairments in the carrying value of U.S. Cellular's license costs, goodwill and/or physical assets.
  
  
• Early redemptions of debt or repurchases of debt, issuances of debt, changes in prepaid forward contracts, changes in operating leases, changes in purchase obligations or other factors or developments could cause the amounts reported under Contractual or Other Obligations in U.S. Cellular's most recent Annual Report on Form 10-K, as updated by the Quarterly Reports on Form 10-Q, to be different from the amounts actually incurred.
  
  
• Changes in accounting standards or changes in U.S. Cellular's accounting policies, estimates and/or in the assumptions underlying the accounting estimates, including those described in Application of Critical Accounting Policies and Estimates included in U.S. Cellular's most recent Annual Report on Form 10-K, as updated by Quarterly Reports on Form 10-Q, could have an adverse effect on U.S. Cellular's financial condition or results of operations.
  
  
• Settlements, judgments, restraints on its current or future manner of doing business and/or legal costs resulting from pending and future litigation could have an adverse effect on U.S. Cellular's financial condition, results of operations or ability to do business.
  
  
• Costs, integration problems or other factors associated with acquisitions/divestitures of properties and/or licenses and/or expansion of U.S. Cellular's business could have an adverse effect on U.S. Cellular's business, financial condition or results of operations.
  
  
• A significant portion of U.S. Cellular's revenues is derived from customers who buy services through independent agents and dealers who market U.S. Cellular's services on a commission basis. If U.S. Cellular's relationships with these agents and dealers are seriously harmed, its wireless revenues could be adversely affected.
  
  
• U.S. Cellular's investments in technologies which are unproven or for which success has not yet been demonstrated may not produce the benefits that U.S. Cellular expects.
  
  
• An inability to obtain or maintain roaming arrangements with other carriers on terms that are acceptable to U.S. Cellular, and/or changes in roaming rates and the lack of standards and roaming agreements for wireless data products, could have an adverse effect on U.S. Cellular's business, financial condition or results of operations.
  
  
• Changes in access to content for data or video services and access to new handsets being developed by vendors, or an inability to manage its supply chain or inventory successfully, could have an adverse effect on U.S. Cellular's business, financial condition or results of operations.
  
  
• A failure by U.S. Cellular's service offerings to meet customer expectations could limit U.S. Cellular's ability to attract and retain customers and have an adverse effect on U.S. Cellular's operations.
  
  
• A failure by U.S. Cellular to complete significant network build-out and system implementation as part of its plans to build out new markets and improve the quality and capacity of its network could have an adverse effect on its operations.
  
  

• A failure by U.S. Cellular's business to acquire adequate radio spectrum could have an adverse effect on U.S. Cellular's business and operations.
  
  
• Financial difficulties of U.S. Cellular's key suppliers or vendors, or termination or impairment of U.S. Cellular's relationships with such suppliers or vendors, could result in a delay or termination of U.S. Cellular's receipt of equipment or services, which could adversely affect U.S. Cellular's business and results of operations.
  
  
• An increase in U.S. Cellular's debt in the future could subject U.S. Cellular to various restrictions and higher interest costs and decrease its cash flows and earnings.
  
  
• An inability to attract and/or retain management, technical, sales and other personnel could have an adverse effect on U.S. Cellular's business, financial condition or results of operations.
  
  
• U.S. Cellular has significant investments in entities that it does not control. Losses in the value of such investments could have an adverse effect on U.S. Cellular's results of operations or financial condition.
  
  
• Changes in guidance or interpretations of accounting requirements, changes in industry practice, identification of errors or changes in management assumptions could require amendments to or restatements of financial information or disclosures included in this or prior filings with the SEC.
  
  
• Uncertainty of access to capital for telecommunications companies, deterioration in the capital markets, other changes in market conditions, changes in U.S. Cellular's credit ratings or other factors could limit or restrict the availability of financing on terms acceptable to U.S. Cellular, which could require U.S. Cellular to reduce its construction, development and acquisition programs.
  
  
• Changes in income tax rates, laws, regulations or rulings, or federal or state tax assessments could have an adverse effect on U.S. Cellular's financial condition or results of operations.
  
  
• War, conflicts, hostilities and/or terrorist attacks or equipment failure, power outages, natural disasters or breaches of network or information technology security could have an adverse effect on U.S. Cellular's business, financial condition or results of operations.
  
  
• Changes in general economic and business conditions, both nationally and in the markets in which U.S. Cellular operates, could have an adverse effect on U.S. Cellular's business, financial condition or results of operations.
  
  
• Changes in facts or circumstances, including new or additional information that affects the calculation of potential liabilities for contingent obligations under guarantees, indemnities or otherwise, could require U.S. Cellular to record charges in excess of amounts accrued in the financial statements, if any, which could have an adverse effect on U.S. Cellular's financial condition or results of operations.
  
  
• Material weaknesses in the effectiveness of internal control over financial reporting could result in inaccurate financial statements or inadequate disclosures or fail to prevent fraud, which could have an adverse effect on U.S. Cellular's business, financial condition or results of operations.
  
  
• The pending SEC investigation regarding the restatement of U.S. Cellular's financial statements could result in substantial expenses, and could result in monetary or other penalties.
  
  
• The possible development of adverse precedent in litigation or conclusions in professional studies to the effect that radio frequency emissions from handsets, wireless data devices and/or cell sites cause harmful health consequences, including cancer or tumors, or may interfere with various electronic medical devices such as pacemakers, could have an adverse effect on U.S. Cellular's business, financial condition or results of operations.
  
  
• U.S. Cellular's assets are concentrated in the U.S. telecommunications industry. As a result, its results of operations may fluctuate based on factors related entirely to conditions in this industry.
  
  
• As U.S. Cellular continues to implement its strategies, there are internal and external factors that could impact its ability to successfully meet its objectives.
  
  
• Any of the foregoing events or other events could cause revenues, customer additions, operating income, capital expenditures and/or any other financial or statistical information to vary from U.S. Cellular's forward estimates by a material amount.
  
  
• The market price of U.S. Cellular's Common Shares is subject to fluctuations due to a variety of factors.
  
  
• Certain matters, such as control by TDS and provisions in the U.S. Cellular restated certificate of incorporation, may serve to discourage or make more difficult a change in control of U.S. Cellular.
  
  
• There are potential conflicts of interests between TDS and U.S. Cellular.
  
  

U.S. Cellular undertakes no obligation to update publicly any forward-looking statements whether as a result of new information, future events or otherwise. Readers should evaluate any statements in light of these important factors.
