FOR RELEASE:  IMMEDIATE

TDS AND U.S. CELLULAR DELAYED IN FILING 2006 FORM 10-K

CHICAGO — March 1, 2007 — Telephone and Data Systems, Inc. [AMEX:TDS, TDS.S] and United States Cellular Corporation [AMEX:USM] today announced that they will be delayed in filing their respective Annual Report on Forms 10-K for the year ended Dec. 31, 2006.

Later today, TDS and U.S. Cellular will each file a Form 12b-25 with the Securities and Exchange Commission related to their Forms 10-K for the year ended Dec. 31, 2006.  The Forms 10-K for the year ended Dec. 31, 2006 are due on March 1, 2007.  By filing the Forms 12b-25, TDS and U.S. Cellular will extend the filing deadline for the Forms 10-K to March 16, 2007.  However, the companies do not expect the Forms 10-K to be completed by the extended deadline of March 16, 2007.  Accordingly, TDS and U.S. Cellular’s Forms 10-K for the year ended Dec. 31, 2006 will not be filed on a timely basis.  TDS and U.S. Cellular expect to file the Forms 10-K as promptly as possible.

The time spent on the restatement of prior period financial statements caused the companies to be late in the filings of their Forms 10-Q for the quarter ended Sept. 30, 2006.  The restatement, which was announced on Nov. 6, 2006, was to correct the accounting for prepaid forward contracts and for out-of-period adjustments and errors.  Both companies completed their restatements and filed their Forms 10-Q for the quarter ended Sept. 30, 2006 on Feb. 23, 2007.

TDS and U.S. Cellular have notified the American Stock Exchange of the delay in filing their Forms 10-K for the year ended Dec. 31, 2006.  Both companies expect to receive AMEX and NYSE notices of failure to satisfy listing requirements as a result of their late filings.  TDS and U.S. Cellular expect to restore compliance with such listings when they file their Forms 10-K for the year ended Dec. 31, 2006.

As disclosed on Feb. 12, 2007, both companies have received from their lenders under credit agreements and from counterparties under certain forward contracts extended waivers to file their Forms 10-K by April 24, 2007.

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.

·A failure to successfully remediate existing material weaknesses in internal control over financial reporting in a timely manner or the identification of additional 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 restatement of financial statements by U.S. Cellular and related matters, including resulting delays in filing periodic reports with the SEC, could have an adverse effect on U.S. Cellular’s credit rating, liquidity, financing arrangements, capital resources and ability to access the capital markets, including pursuant to shelf registration statements; could adversely affect U.S. Cellular’s listing arrangements on the American Stock Exchange and/or New York Stock Exchange; and/or could have other negative consequences, any of which could have an adverse effect on the trading prices of U.S. Cellular’s publicly traded equity and/or debt and/or 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.
