since i updated my iphone to the 3.0 i only receive about 1 out 5 calls and many of my text messages are late. ive tried restoring and all that. im at a bit of a dead end.
As an update, I talked to one of my friends today that is on AT&T, also. He has a Motorola slider and tells me that he is also getting text messages late, sometimes up to a day or two.
