Charging time doesn't seem any different than my T637. The battery used in this phone is the same as the V3 RAZR, so is the charger.

I have Cingular's Media Works package which is unlimited data for $20 per month. EDGE doesn't cost anything more, but I think if you have a Blackberry or Palm phone, you have to pay more for unlimited data since they view these to be primarily data devices. It sucks, but I hear that's how it works. I don't know if they will be able to tell what my phone is now, but I signed up for Media Works with the T637.
