The last few times i've been to Dallas sporting events with my iPhone, it has just acted strangely. Last week on the way to Texas stadium, my phone: showed five full bars of 3G, but would not actually connect anywhere or make a call. even when i manually turned off 3G, it still showed 5 full bars of 3G... but was essentially a paperweight, communications-wise. so i restart. it comes up No Service for about 5 minutes. Then shows 2 bars of EDGE, and seems to be connecting online... Then back to 5 bars of 3G. Except this time, now it is fluctuating between 3-5 bars 3G... still unable to connect or even make a call. Even when turning off 3G, i still got the same fluctuating-but-strong 3G connection / no connection. The ballpark did the same sort of thing... showing connected but not actually connected. anybody else get this?
