I was up in ME this weekend with my new iPhone 3G. I had no service up there, and was low on battery power (Is it just me, or to the iPhones use lots of power when there's no service???). So, I turned her off, just in case I needed to make a call on the way home. When I got home, I charged her up, and turned her on. But, there was no service down here either. I shut it off and turned it back on again, but still no service? I tried calling my phone from my house landline, but it gave me a "the subscriber you're trying to reach hasn't set up a voicemail box yet" instantly (I hadn't set up the VM...). About 5 minutes after that (An hour of total No Service at home), I was greeted with 5bars of 3g... Was it that AT&T was expecting my phone in Maine, so it couldn't find me in Boston? Or was there an issue with the service? Or is there an issue with my phone????
