Practically every carrier out there is looking to see if VoIP will
work on their networks. The short answer says Nextel's lock on PTT is
about to end.

Nope.

PTT either requires a protocol written from the ground up to support it
(i.e., iDEN) or a protocol with advanced extensions; GSM is not advanced or
extensible enough to support that, only CDMA is.

The only way Cingular would be able to implement PTT would be to change
their underlying (GSM) architecture, which is NOT going to happen anytime
soon.

No, PTT works like a walkie talkie -- no need to make and keep a connection --
instant connect and disconnect. For those that need it, it's pretty handy and
efficient.
