      This Schedule 13G amends with respect to AT&T Corp. ("AT&T") the statement
on Schedule 13G initially filed by AT&T Wireless PCS, LLC, Mary Hawkins-Key and
AT&T on February 14, 2000. This amendment is being filed to reflect the
split-off of AT&T Wireless Services, Inc. from AT&T on July 9, 2001, as a result
of which AT&T Wireless Services, Inc. became an independent, publicly traded
company. Consequently, AT&T no longer has any beneficial ownership of the Class
A Common Stock of Triton PCS Holdings, Inc.

third and fourth sentences and replacing them in their entirety with the
following:

a result of which AT&T Wireless Services, Inc. became an independent, publicly
traded company. Consequently, AT&T may no longer be deemed to be the beneficial
owner of AT&T Wireless PCS, LLC, a wholly owned subsidiary of AT&T Wireless
Services, Inc., and AT&T no longer has any beneficial ownership of the Class A
Common Stock of Triton.
