This Amendment No. 1 to Schedule 13D amends and supplements the Schedule 13D filed on September 26, 2007 (the “Original Schedule 13D”) with respect to shares of Class A common stock, par value $.01 per share, of SunCom Wireless Holdings, Inc., a Delaware corporation (the “Issuer”). The principal executive offices of the Issuer are located at 1100 Cassatt Road, Berwyn, Pennsylvania 19312. Capitalized terms used but not otherwise defined in this Amendment No. 1 shall have the meanings ascribed to such terms in the Original Schedule 13D.

On February 22, 2008, TMUS completed its acquisition of the Issuer pursuant to the Merger Agreement. The acquisition was effected by the merger of Merger Sub with and into the Issuer, with the Issuer surviving the Merger as a wholly owned subsidiary of TMUS. As a result of the consummation of the Merger, on February 22, 2008, the Voting Agreement terminated pursuant to its terms.

After reasonable inquiry and to the best of my knowledge and belief, I certify that the information set forth in this statement is true, complete and correct.
