Item 2. Identity and Background.

The following sets forth information with respect to Items 2(a) through 2(f) for TDS and the Trustees of the Voting Trust.

(a-c, f) TDS and the Trustees of Amendment and Restatement (dated as of April 22, 2005) of Voting Trust under Agreement dated June 30, 1989 (the “Voting Trust”), are filing this Schedule 13D amendment concerning their direct and indirect beneficial ownership of Common Shares.

TDS. TDS is a Delaware corporation. The principal business and office address of TDS, is 30 North LaSalle Street, Suite 4000, Chicago, Illinois 60602. TDS’ principal business is that of providing diversified telecommunications services. TDS, directly and through its subsidiaries, has wireless, local telephone, and broadband services operations. The information with respect to the directors and executive officers of TDS is set forth on Appendices A and B attached hereto, and incorporated herein by reference.

The Trustees of the Voting Trust. The principal business address of the Voting Trust is c/o TDS, 30 North LaSalle Street, Suite 4000, Chicago, Illinois 60602. The Voting Trust holds TDS Common Shares and TDS 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 TDS Series A Common Shares held in the trust. The information with respect to the trustees of the Voting Trust is set forth in Appendix C hereto, and incorporated herein by reference.

(d) To the knowledge of LeRoy T. Carlson, Jr., during the last five years, none of TDS, the Voting Trust, nor any of the persons named in Appendices A, B and C hereto has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors).

(e) To the knowledge of LeRoy T. Carlson, Jr., during the last five years, none of TDS, the Voting Trust, nor any of the persons named in Appendices A, B and C hereto was a party to a civil proceeding of a judicial or administrative body of competent jurisdiction, and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

Item 3. Source and Amount of Funds or Other Consideration.

The information contained in Item 4 below is incorporated herein by reference.

Item 4. Purpose of Transaction.

TDS and the Voting Trust have changed their intent and have decided to initiate a process (the “Strategic Process”) to explore a range of potential strategic alternatives (each, a “Strategic Alternative”) regarding the Issuer.

Strategic Alternatives could take a variety of forms and may result in one or more of the matters specified in (a) through (j) of Item 4 of Schedule 13D.

In connection with the Strategic Process, TDS has engaged and expects to continue to engage in discussions with directors and officers of the Issuer and expects to engage in discussions with third parties (subject to appropriate confidentiality or similar agreements). It is possible that no Strategic Alternative will ultimately be consummated.

The trustees of the Voting Trust have advised TDS that they intend to maintain the ability to keep or dispose of the voting control of TDS. The trustees of the Voting Trust have further advised TDS that, if and to the extent that the Issuer remains a publicly-traded company, the trustees of the Voting Trust intend that TDS maintain the ability to keep or dispose of the voting control of the Issuer.

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