APPELLATE COURT AFFIRMS ILLINOIS TRIAL COURT DECISION

Court Affirms Ruling That Sprint Must Cease Owning, Operating and Managing
Nextel Network in iPCS Wireless’s Territory

SCHAUMBURG, Ill. — March 31, 2008 - iPCS, Inc. (Nasdaq: IPCS), a Sprint PCS Affiliate of Sprint Nextel, announced that today the Illinois Appellate Court affirmed the 2006 decision of the Circuit Court of Cook County, Illinois requiring Sprint to cease owning, operating and managing the Nextel wireless network in iPCS Wireless’s territory.

The Appellate Court held that the trial court did not err when (i) it considered extrinsic evidence and found that the management agreement prohibited Sprint from operating in iPCS Wireless’s territory because Sprint violated the terms of the agreement, and (ii) it entered an order for a mandatory injunction and ordered the divestiture of Sprint’s Nextel holdings in iPCS Wireless’s territory.  Accordingly, the Appellate Court affirmed the decision of the Circuit Court.

“We are pleased that the Appellate Court affirmed the decision of the trial court,” remarked Timothy M. Yager, President and CEO of iPCS.  “This is a significant victory for iPCS and we look forward to Sprint’s compliance with the Circuit Court’s 2006 order,” continued Mr. Yager.

iPCS Wireless, an operating subsidiary of iPCS, Inc. manages a territory with approximately 7.8 million licensed pops in portions of Illinois, Michigan, Iowa and eastern Nebraska.

This press release, along with a copy of the Appellate Court’s decision, is being filed with the SEC as part of a Form 8-K. We encourage you to read the Appellate Court’s opinion in its entirety.
