    For whatever reason, I keep noticing that my iPhone will go into GPRS mode (where the 3g/edge logo turns into a circle) when I'm on a call. I live in Los Angeles and as soon as I get off the phone I can see the circle logo which back to the E or 3g logo. I have also noticed a major deterioration in voice quality since noticing the reversion to GPRS. Has anyone else come across this? Is there a fix? Does apple/ATT even know about this?

    Thanks

    3g iPhone with OS 2.2

    It depends, if your driving then the problem is that as soon as you get out of a 3G area then it will not come back until you hang up;you can't use edge while on the phone anyways. If you are in the same spot and it is happening (if you have 3G) then try resetting your network settings; if problem continues, then go to AT&T and get a new sim card. If all fails, then tell him he needs a new phone (Visit Apple for that). Hope that helps:cool:

    Thanks. It occurs when I'm driving, when I'm sitting at my desk, etc. It is hard to believe that Los Angeles isn't completely covered in 3g, let alone EDGE!

    When driving I guess is normal. I mean even if you lose 3G for 5 seconds it won't come back until you hang up (which stinks). While sitting at your desk though is something else. I think its more of the iPhone problem since this happens to me alot; example, at work I stand in the same spot and have 3 bars of 3G, then when I look, I have 5 bars of edge. Just standing in the same spot it switches back and forth. Try what I told you but I am pretty sure it is normal.

    It does it to me too. I always assumed the reason was that it was intelligent enough to switch down during a call to save power, because UMTS 3G uses more power than 2.5G GPRS/EDGE, given that the quality of the call stays the same regardless of the transport - which is my experience.
