Your phone won't work on T-Mobile. Any phone using its service is going to be GSM and in order to use Verizon's network, it has to not only be CDMA, but authorized for use as well.
You do know that Verizon now carries a line of GSM phones right? They are GSM/CDMA. Thing is, I think you are right in regards to Verizon and the HTC Excalibur (Tmobile DASH) .. which sucks.... nonetheless I have some other plans ..
Last night I used our wireless connection here at home to surf the internet on the wifi of this phone! The wifi works, whether or not cell phone service through a carrier is enabled or not.
What I would like to do then is turn this thing into a wifi phone and use it with skype/gizmo/grand central -- unbrand it and unlock it as well.
sounds like a fun project, eh? The phone was working with skype messaging last night off of its wifi, I did not test the calling features. I want to have it unbranded and unlocked before i start trying to make wifi calls.
BTW, skype is now selling mobile wifi phones. none of them have a handy dandy qwerty keyboard like this phone does, though.
