Mine was whatever was free when my father renewed the plan. It works for most of what I've been using my phone for, text messages and calling. It came with a few games that helps pass the time and the camera isn't bad. Web functions are a little limited tho.
I've been wanting a cell that doubled as a handheld PC and had actual wireless access to the net. Of course that wont happen until I get off the family plan.
As for service... I'm sadly stuck with AT&T. Don't get me wrong, when it was cingular the service was AWESOME. But for some reason the second my phone started displaying AT&T it was like they DOWNGRADED their towers or something. Service is piss poor. My father is pissed, and he's been with the company since the early 90s. Can't even get connection inside the house anymore...
