Sounds reasonable to me. By eliminating the phone's need to switch from 3G to EDGE, maybe I've worked around several of the reasons that the iPhone drops calls. Funny that AT&T with all its resources can't adequately explain this -- or point a finger at Apple.
Okay, the iPhone is NOT the only 3G smartphone on AT&Ts network. Ever here of anyone else complaining about their smartphone? How about Droid users on Verizon?
I suspect there is a bug in switching towers when 3G is enabled. If I had to make a guess, it would be that the degrade from 3G to Edge is too slow. Because of this, it stays in 3G mode just a bit too long and drops the call. I think it is trying to hold up the data rate on the data connection it has. Once you turn 3G off, you don’t have that switch go on. It basically is just doing cell switching. There are multiple cases here and I think 1 of them does not work reliably.
It could be an iPhone issue, sure. Perhaps the radio for 3G just sucks? I dunno. I do know that with 3G off, my calls are louder, clearer, and I can maintain them even -- gasp! -- when I'm moving around.
I guess the data volume of the 3G network is higher. But what else contributes to better 2G calls? Is this happening just because the 2G network is more mature? Better codecs and whatnot? Anyone care to venture a technical guess?
