FOR RELEASE: IMMEDIATE

TDS AND U.S. CELLULAR RECEIVE ADDITIONAL EXTENSIONS FROM AMEX

CHICAGO - Jan. 22, 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 Feb. 12, 2007 to regain compliance with listing standards. TDS and U.S. Cellular previously received extensions to Feb. 12, 2007 from lenders under their revolving credit agreements and counterparties under certain forward contracts.

The companies will regain compliance with AMEX listing standards when they file their Forms 10-Q for the quarter ended Sept. 30, 2006 with the Securities and Exchange Commission (SEC). Previously, the AMEX had notified both companies that it had accepted their plans to regain compliance and had granted both companies an extension until Jan. 22, 2007. TDS and U.S. Cellular expect to file their results for the quarter ended Sept. 30, 2006 as soon as possible, on or before Feb. 12, 2007. During the extension period, both companies are subject to periodic review by the AMEX.

The companies did not file their Forms 10-Q on a timely basis because both companies decided to restate financial results for the first and second quarters of 2006 and each of the years ended Dec. 31, 2002 - 2005, including quarterly information for 2004 and 2005. The restatement is primarily due to the correction of the accounting for prepaid forward contracts under Statement of Financial Accounting Standards (SFAS) No. 133, Accounting for Derivative Instruments and Hedging Activities. In connection with the restatement of prior period financial results relating to SFAS 133, TDS and U.S. Cellular identified a number of out-of-period adjustments related to revenues and expenses that previously were recorded in the financial statements but not in the proper periods. The additional adjustments are significant for certain prior periods. Therefore, in light of the decision to restate, the company considered it appropriate to include these adjustments in the restatement.
