Google Maps GPS has been a dream for a long time. It's about time.. All my friends are on ATT right now.. but it's going to be really hard for me to avoid getting a Droid when it comes out. Anyone know if its chipset supports GSM-based networks like ATT? If so - me thinks I'll be getting an unlocked one.
