This is a not a temporary problem. Apple has been passing the blame on AT&T all these months about drop calls. I have personally done this experiment numerous time now. I place my 3GS and a $20 phone side by side(both AT&T). Called my wife twice - 3GS says called failed, $20 phone works first time. Tried calling from $20 phone to my iphone which just next to it, can hear 5 rings than goes the my voice mail - 3GS doesn't ring at all. Ofcourse iphone 3GS can call out after couple of call failed msg. When we goto apple - same standard stupid questions Its AT&T bad reception, please change to edge from 3GS in the network settings. Did to recycle the phone? - when i hear this, reminds me you windoz 95 Did you upgraded to latest patch? Recently, apple took out the application which suggests number dropped calls on iphone from their genius bar :-) Now, before you start talking about dropping calls - they are ready with a new iphone for you. Isn't that a joke - apple accepting the fact that iphone are really screwed up if you are using it as a phone. I cannot even imagine upgrading myself to 4GS now.

thats so true.. they have mutilated the old FreeBSD so bad and still never hesitate to call it unix underneath...
