iPCS, Inc. Announces Subscriber Activity for the Quarter Ended March 31, 2008.

Schedules Earnings Release and Conference Call to Discuss Results

SCHAUMBURG, Ill. -- iPCS, Inc. (Nasdaq: IPCS), a Sprint PCS Affiliate of Sprint Nextel, today announced that it serves approximately 640,600 customers as of March 31, 2008.

For the quarter ended March 31, 2008, iPCS reported:

* Gross additions of approximately 59,200

* Net additions of approximately 10,700

* Average monthly churn, net of 30 day deactivations, of approximately 2.3%

* Ending subscribers of approximately 640,600

"First quarter gross additions were in line with our expectations. Our net additions however were much stronger than expected as churn came down from the levels we experienced in the latter half of 2007. Our customer-focused initiatives and the programs at Sprint showed good momentum for the quarter," commented Tim Yager, President and Chief Executive Officer.

"These subscriber metrics, along with the Illinois Appellate Court's unanimous affirmation of the lower court's ruling requiring Sprint to cease owning, operating and managing the Nextel wireless network in iPCS Wireless's territory, have provided for an excellent start to 2008," Yager concluded.
