I am thinking of getting an Unlocked GSM Treo 650 for use on Cingular. One question. Will the Unlocked/Unbranded version of the Treo 650 work with Edge when activated with Cingular SIM? or Will Edge only work with the Cingular version? Thanks
The unlocked works fine. The Cingular sim is the brains of the phone - as it works, you get edge speeds.
Treo 750 and iPhone.
Mine worked as soon as I inserted the SIM card.
