Introductory Note:

         Michael E. Kalogris hereby files this Amendment No. 1 to Schedule 13D
(this "Amendment") to amend the Schedule 13D (the "Original 13D") filed with the
Securities and Exchange Commission (the "Commission") on May 28, 2004. This
Amendment and the Original 13D relate to the Class A Common Stock, par value
$0.01 per share (the "Common Stock"), of Triton PCS Holdings, Inc. (the
"Issuer"). Except as modified herein, the Original 13D is unmodified.


Item 6.  Contracts, Arrangements, Understandings or Relationships With Respect
         to Securities of the Issuer.

         The  disclosure under this Item 6 in the Original 13D is hereby
incorporated by this reference and amended by adding the following paragraph to
the end of such disclosure.

         On July 7, 2004, the Issuer, AT&T Wireless Services, Inc., AT&T
Wireless PCS LLC and Cingular  Wireless LLC entered into an agreement pursuant
to which AT&T Wireless PCS LLC has agreed to deliver and surrender to the Issuer
all of the Issuer's stock held by it, including 786,252.64 shares of the
Issuer's Series A Preferred Stock and 543,683.47 shares of the Issuer's Series D
Preferred Stock (collectively, the "AT&T Owned Stock") upon and subject to the
consummation of the acquisition of AT&T Wireless Services, Inc. by Cingular
Wireless LLC and subject to the satisfaction of certain other closing
conditions. Pursuant to this agreement, upon the surrender by AT&T Wireless PCS
LLC of the AT&T Owned Stock, the Issuer's First Amended and Restated
Stockholders Agreement dated October 27, 1999, as amended, will terminate.  In
this regard, the First Amended and Restated Stockholders Agreement also has been
amended to specifically provide for termination upon delivery and surrender of
