CHICAGO – May 7, 2008 – United States Cellular Corporation [AMEX:USM] reported service revenues of $962.1 million for the first quarter of 2008, an 11.8 percent increase from $860.6 million in the comparable period one year ago. The company recorded operating income of $119 million, an increase of 9.6 percent from $108.5 million in the first quarter of 2007. Net income and diluted earnings per share were $70.6 million and $0.80, respectively, compared to $74.4 million and $0.84, respectively, in the comparable period one year ago.*

*In the first quarter of 2007, the company recorded a $12.5 million pre-tax gain on fair value adjustment of derivative instruments related to the derivative component of the Vodafone Group Plc variable prepaid forward contracts.

Continued growth in data revenues drives service revenues and ARPU

“U.S. Cellular experienced strong growth in data revenues this quarter,” said John E. Rooney, U.S. Cellular president and CEO, “driven in part by new smartphones like the BlackBerry® Pearl™ and their related data plans, and by customers’ increased use of messaging services. The 49 percent increase in data revenues helped to drive up both service revenues and ARPU. The growth in service revenues was partly offset by growth in operating expenses, however, resulting in lower margins. We also had solid net retail customer additions in the quarter, and maintained a low, 1.4-percent retail postpay churn rate.

“We continue to focus on providing a consistently high-quality wireless experience,” added Rooney, “in terms of network strength and reliability and exceptional customer service. We received our fifth consecutive J.D. Power and Associates award for call quality this quarter, and our associates are committed to exceeding our customers’ expectations for service and satisfaction.”

Strengthened footprint with new spectrum

U.S. Cellular participated in Auction 73, the Federal Communications Commission (FCC) auction of spectrum in the 700 MHz band, through its interest in King Street Wireless L.P. King Street Wireless was the provisional winning bidder for 152 licenses for an aggregate bid of $300.5 million, net of its designated entity discount, which was recorded in licenses on U.S. Cellular’s balance sheet as of March 31, 2008. The FCC has not yet awarded any of the licenses to winning bidders. The licenses expected to be awarded to King Street Wireless cover areas that overlap or are proximate or contiguous to areas covered by licenses that U.S. Cellular currently owns, operates, and/or consolidates in its financial statements.

Guidance

Guidance for the year ending Dec. 31, 2008 is as follows. There can be no assurance that final results will not differ materially from this guidance.

U.S. Cellular 2008 guidance as of May 7, 2008 is as follows:

Net Retail Customer Additions		200,000 - 275,000
Service Revenues		$3.9 - 4.0 billion**

Depreciation, Amortization & Accretion		Approx. $615 million**

**Unchanged from guidance issued on Feb. 29, 2008

The foregoing guidance represents the views of management as of May 7, 2008 and should not be assumed to be accurate as of any other date. U.S. Cellular undertakes no legal duty to update such information, whether as a result of new information, future events, or otherwise.
