Why is 2G call quality better than 3G?

instead of being a jerk to your friend, did you try his recommendation? at the very least it would save you some battery, so it wouldnt hurt to try. 3G is only beneficial for its faster data transfer.

Are you generally that rude to your friends? Try turning 3G off and see if call quality improves. My house is in a marginal 3G area and making calls with 3G is choppy because the phone is switching in and out of 3G. If I turn off 3G, call quality is excellent and my battery life is incredible. If I'm out of a wifi area and in 3G, I turn 3G on for data.

IMHO, audio quality improved tremendously with firmware 2.1 regardless of which phone
I was using. Maybe you actually have a phone or service problem.

It does affect call quality. The quality on my 3G is significantly better when on 3G then when I'm in an area only with EDGE. Others I know with the 3G have experienced the same thing.

It is just in your opinion that the 3G is inferior to the first iPhone. It is hard for me to call the 3G inferior just because PatrickL says so.

I am assuming that you have been through all the troubleshooting steps such as Reset, Resetting your network settings, Restore, etc. If you have and that does not help then get your phone serviced. And do remember that your call quality, i.e. how good you sound is also impacted by the signal quality of the person you are talking to.

It's amazing how afraid everyone seems to be to call the 3G iPhone what it is--inferior to the 2G. Is that so hard to do?

i guess thats why i still have my first-gen phone and didnt upgrade to 3G.

I could be wrong but I was always under the impression that 3G and EDGE are only for data and have nothing to do with voice calls.

My phone is fine. If you read my post, you would have noticed I said I'm in a marginal 3G area.
