Forgive me if this has been posted before. I experience 3G issues going from wifi in my house, then getting in the car and leaving..the 3G data service does NOT turn on. I usually have to power off the phone, or sometime dialing *228 and selecting option sometimes works. It's just really annoying when I really need the data service for directions or GPS service, or need to check or send an email when I'm on the go. Anyone else have this problem?
