I am moving out of AT&T's coverage area at the end of this month, so I decided to switch to Verizon before the unlimited data goes away. I am completely amazed. 3G is super fast. I have had AT&T for three years, and two iPhones (3G and 4), and I have never seen speed like this. Checking email is instantaneous. A video call over Skype doesn't drop or get fuzzy or out of sync. I can watch an entire Netflix movie without it just stopping in the middle and wait for it to remember to buffer. I haven't used it much for voice yet, but the test will be when I have my weekly phone call with my dad on Sunday. He always complains that he can't hear me, so we'll see if he can hear the difference now. I have never been someone who complained about AT&T. I have always lived in metro areas that I thought got pretty good AT&T coverage. My iPhone 3G was the first smartphone I ever had, so I never realized that data speeds should be any different. Now I know the truth.
