So I took my iPhone on a 2 week trip to the UK & France. We had a lovely vacation, took many pictures, romantic walks along the Siene. We plan on going back soon. I Blackra1ned & Blacksnow'd a couple of weeks before I left. It crashed every couple of days and had to restore a few times. So I was afraid this would happen when I went overseas but the iPhone worked wonderfully on Orange. Never crashed, never lost my WiFi, never had to do a frustrating restore. Just perfect. I never got lost thanks to Google Maps & GPS. So I got back to the US on Monday night and had popped my AT&T SIM back in before I landed, turned it on...seems ok. Last night, it crashed twice. Today, completely shut off and I couldn't get it to turn back on w/o restoring it. I find it hard to believe that AT&T could do that but is it possible? I know it sounds naive but I just find it so odd. Anyone else run into this or heard of these issues?
