it's been about a day and a half since i've made the switch from verizon to at&t. i was afraid to do this since everyone mostly has verizon where i live. the signal at home is at the very least 2 bars and at the very best 4 bars. not bad. i updated to the firmware 2.2 on the iphone. i noticed i was not able to receive SMS from any other carriers except at&t after this update. i'm not sure whether it could have been the cause..or i'm just a new customer. hmm. i was on the phone with technical support for a little over an hour trying to figure out the issue and eventually it was resolved. i started receiving phone calls and text messages "why aren't you answering my calls?!" and "it's about time you pick up!" so, it seems i'm only getting 80% of the calls, which to me is not acceptable. voicemail also seems to be delayed. i really LOVE the phone and all of the awesome features. i hate to get rid of it, but it looks as though this may be the end result. i'm not really asking for advice, i guess i just wanted to put that out there. a phone really is only as good as the network it's on..
