I had AT&T for over a year and the service was great for the firs 3+ months, then the signal started dropping where I live and work. It was great everywhere else, but I started suffering dropped calls. Went to AT&T and they said they'd look into it. Nothing happened. Went back. They said "turn off 3G." I tried toggling 3G for important phone calls, and it helped, but of course, hobbled the data connection. In late 2010 and into 2011, I was getting dropped calls regularly. Upgraded to a 3Gs phone, and it was a little better, but not acceptable. Switched to Verizon the day the iPhone became available. One dropped call in 4 months. The incoming call handling sucks and the inability to use the internet during a call is a small tradeoff. The data speed on Verizon is about 60% of what it was on AT&T. Net: it didn't solve all the problems, but the iPhone is 100% better for making calls on Verizon than AT&T.
