The
SX56 Pocket PC Phone from Siemens, a virtual
twin of T-Mobile's Pocket PC Phone, was sold
by AT&T
Wireless in 2003. Running Pocket PC 2002 Phone
Edition, the SX56 was the first Pocket PC/Phone
hybrid working on the AT&T wireless
network.
The SX56 is now in limited distribution and was
replaced by the SX66 in
mid-February 2005. The SX66 is
available for the Cingular wireless network,
which recently absorbed AT&T Wireless.
Other
Pocket PC Phones are also available. They
