If they knew how many calls the iPhone 4 dropped they wouldn't be interested in getting one.
That's not the iPhone dropping the calls. That's AT&T crappy service doing that. I left them years ago having multiple drops, even being within 100 feet of there towers, and went to sprint. Allot better. I would have bought an iPhone over the evo in a heart beat if offered on sprint. Evo is ok but knowing the critical security flaws with android, my next phone will be either blackberry or iPhone if it's available.
