Item 3.

The Voting Trust holds Special Common Shares and Series A Common Shares pursuant to the voluntary agreement of the beneficiaries thereof.  No funds were used by the Voting Trust to acquire any shares.  This Schedule 13D is being filed to report the acquisition of 6,067,519 Special Common Shares by the Voting Trust on May 13, 2005 pursuant to the Distribution, as defined in Item 4.

Item 4.

Purpose of Transaction.

The Voting Trust holds Special Common Shares and Series A Common Shares and was created to facilitate long-standing relationships among the trust’s certificate holders.  Under the terms of the Voting Trust, the Trustees hold and vote the Special Common Shares and Series A Common Shares held in the trust.

The following information was reported in Amendment No. 3 to the Schedule 13D of the Voting Trust with respect to the Common Shares and is being updated herein.

The Voting Trust was amended and restated as of April 22, 2005 for the primary purpose of permitting the Trustees of the Voting Trust to retain and vote the Special Common Shares of the Issuer that were received by the Voting Trust as a result of the Distribution, as defined below.   In addition, certain other changes were made to the Voting Trust agreement, which is incorporated by reference herein.  On February 17, 2005, the TDS Board of Directors (the “TDS Board”), including directors who are not trustees or beneficiaries of the Voting Trust, and directors who are not officers of TDS, unanimously approved a proposal (the “Special Common Share Proposal”), to be submitted to TDS shareholders at a Special Meeting of shareholders, to approve an amendment (the “Amendment”) to the Restated Certificate of Incorporation of TDS to increase the authorized number of Special Common Shares of TDS from 20,000,000 to 165,000,000.    The Voting Trust had the voting power to cause the Special Common Share Proposal and certain related proposals to be approved, and the trustees of the Voting Trust advised TDS that they intended to vote for the Special Common Share Proposal and for such related proposals at the Special Meeting of shareholders.  The Special Common Share Proposal and related proposals were approved at the Special Meeting of shareholders and the Amendment became effective on April 11, 2005.

The trustees of the Voting Trust were advised that the Special Common Share Proposal is being implemented by TDS, among other reasons, to permit TDS at some time in the future to offer and issue Special Common Shares in exchange for all of the Common Shares of United States Cellular Corporation (“U.S. Cellular”) which are not owned by TDS (a “Possible U.S. Cellular Transaction”).  Subject to certain conditions, the trustees of the Voting Trust have advised the TDS Board that they may also support such possible action by TDS.  TDS currently owns approximately 82% of the shares of common stock of U.S. Cellular.  The purpose of a Possible U.S. Cellular Transaction would be to cause U.S. Cellular to become a wholly-owned subsidiary of TDS.

The TDS Board has approved a distribution of one Special Common Share in the form of a stock dividend with respect to each outstanding Common Share and Series A Common Share of TDS (the “Distribution”), subject to the approval of the Special Common Share Proposal by shareholders, the effectiveness of the Amendment, and certain other conditions.   Each of these conditions was satisfied and the Distribution became effective on May 13, 2005 to shareholders of record on April 29, 2005.

As of May 13, 2005 (on a pro forma basis based on shares outstanding on April 29, 2005), the Voting Trust had voting or dispositive power over an aggregate of 6,067,519 Series A Common Shares, representing approximately 52.5% of the voting power of TDS with respect to matters other than the election of directors. Based on such shares, the Voting Trust received 6,067,519 Special Common Shares in the Distribution.  Following the Distribution, the Voting Trust continues to have 52.5% of the aggregate voting power of TDS with respect to all matters other than the election of directors and continues to be able to elect eight of the twelve directors by reason of its ownership of 6,067,519 Series A Common Shares.  As a result of the Distribution of 6,067,519 Special Common Shares to the Voting Trust, the Voting Trust also has 5.6% of the voting power in the election of the four directors currently elected by the holders of Common Shares of TDS.

Implementation of the Special Common Share Proposal and the Distribution allows TDS to issue such Special Common Shares for a Possible U.S. Cellular Transaction and other corporate purposes without diluting the voting power of the Series A Common Shares and the voting control of the Voting Trust.  As a result, the trustees of the Voting Trust also advised TDS that they may support a Possible U.S. Cellular Transaction.  The trustees advised TDS that they would not support or approve various actions, including a sale of control of U.S. Cellular or a spin-off of U.S. Cellular. The trustees of the Voting Trust also advised TDS that they did not believe that certain other possible alternatives would be in the best interest of TDS and all of its shareholders and, accordingly, would not approve or support action in furtherance of such alternatives.  The trustees of the Voting Trust intend to maintain the ability to keep or dispose of the voting control of TDS and intend that TDS maintain the ability to keep or dispose of the voting control of U.S. Cellular.

The trustees of the Voting Trust have been advised that the TDS Board has not taken any action to determine that it will offer Special Common Shares, or the number of Special Common Shares or fraction of a Special Common Share that it may offer, to exchange for each Common Share of U.S. Cellular not owned by TDS.

The trustees of the Voting Trust also have been advised that TDS has no set time frame for taking action with respect to a Possible U.S. Cellular Transaction and TDS could choose to take action with respect to a Possible U.S. Cellular Transaction at any time, or not to take action with respect to a Possible U.S. Cellular Transaction, depending on the circumstances at the time.  The trustees of the Voting Trust have been advised that the timing of such possible transaction also depends on the trading price of the U.S. Cellular Common Shares, the trading price of the Special Common Shares, market conditions and other factors, including whether any possible transaction would be likely to be disruptive to U.S. Cellular’s operations.

If a Possible U.S. Cellular Transaction does not take place for any reason, U.S. Cellular may not become a wholly-owned subsidiary of TDS and the Common Shares of U.S. Cellular may continue to be publicly traded. The trustees of the Voting Trust have been advised that TDS may alternatively consider acquiring such Common Shares of U.S. Cellular through open market or private purchases, or taking other action to acquire some or all of the shares of U.S. Cellular not owned by TDS.

Reference is made to the description of the Special Common Share Proposal under Proposal 1 in the definitive proxy statement of TDS filed with the SEC on March 14, 2005 for additional information relating to the foregoing, which description is incorporated by reference herein.

Reference is also made to the description under Proposal 1 – Election of Directors in the definitive proxy statement of TDS filed with the SEC on April 5, 2005 for information relating to the election of directors, which description is incorporated by reference herein.

Except as disclosed or incorporated by reference above, the Voting Trust does not have any current intention, plan or proposal with respect to: (a) the acquisition by any person of additional securities of the Issuer, or the disposition of securities of the Issuer; (b) an extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving the Issuer or any of its subsidiaries; (c) a sale or transfer of a material amount of assets of the Issuer or any of its subsidiaries; (d) any change in the present board of directors or management of the Issuer, including any plans or proposals to change the number or term of directors or to fill any existing vacancies on the board; (e) any material change in the present capitalization or dividend policy of the Issuer; (f) any other material change in the Issuer's business or corporate structure; (g) changes in the Issuer's charter, bylaws or instruments corresponding thereto or other actions which may impede the acquisition of control of the Issuer by any person; (h) causing a class of securities of the Issuer to be delisted from a national securities exchange, if any, or cease to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association; (i) a class of equity securities of the Issuer becoming eligible for termination of a registration pursuant to Section 12(g)(4) of the Act; or (j) any action similar to any of those enumerated above.

Notwithstanding the foregoing, the trustees of the Voting Trust retain the right to change their intent, including to acquire additional securities from time to time, or to dispose of all or part of the securities beneficially owned by the Voting Trust in any manner permitted by the terms of the Voting Trust and applicable law.

Item 5.

The Special Common Shares have no votes in matters other than the election of such directors except as required by law.  The holders of Series A Common Shares are entitled to elect eight of the twelve directors of the Issuer.  The Series A Common Shares also have ten votes per share in matters other than the election of directors and, accordingly, the Series A Common Shares held by the Voting Trust represent approximately 52.5% of the combined voting power of the Issuer.(1)  Therefore, the Voting Trust elects a majority of the directors and directs a majority of the combined voting power of the Issuer in matters other than the election of directors.
