    Cingular has added a Push to Talk service similar to Nextel. Does anyone know if the 650 can be upgraded to use this feature?

    Nope. Not at this time anyway. I heard a rumor once that they're working on a patch to add the capability but then I heard rumors that they won't be doing any firmware upgrades to incude it on current phones. I really hope the first rumor is true. PTT would be great on the Treo!
    My Treo's Stats:
    650 Unlocked/Unbranded GSM <br>1.71 Firmware w/ 1.20 ENA
    Carrier: Cingular
    Current BT Headset: Treo Wireless
    GPS: TomTom5 + BT338

    It makes you wonder what the side button was put there for, if not to potentially become a PTT button. I guess it was nice to have it built in in case they decided to support it, but my experience with PDAs is that the manufacturer would rather you spend another $500 for a new model than to add major features through patches to the old ones, even if the hardware could support such an upgrade.
