It's only available thru AT&T from what I know. It's really a nice phone...I had two T68i's that would only get reception about 50% of the time from my house. So far, the 525 has never dropped a call. My only complaints so far are:
-no active flip
-no cradle charger
-the camera is only so/so (especially in low light)
-the keypad has green lights
To me, the rest of the features, and the AMAZING screen on this phone make up for the minor shortcomings. Hopefully there will be a firmware update to fix some of my minor complaints.
