I just bought an iPhone 3G from AT&T a few hours ago. I live in area with great AT&T reception (5 bars, currently) and it has 3G coverage. However, my iPhone cannot connect to the internet at all, nor does it have GPRS services. I've verified that airplane mode is off and 3G is enabled. I've also tried updating the firmware to 2.0.2 (it came with 2.0.1) and restarting the iPhone via the on/off switch. Any suggestions?
