I Just called Verizon to find out what my early termination charge would be. It's $270. To upgrade to the 4S on Verizon would cost $650. To switch to At&T would cost 270 plus 199, total of $470. So it would be a $180 cheaper to switch to At&t. I think the monthly was also lower on At&T. While I have been happier, overall on Verizon, it hasn't been that noticeable. I would be giving up unlimited data, but I use only about 1gb a month anyway. I pointed all this out to the verizon rep, and she said there was nothing they could do about it. Quoted 40% better reliability and tiered text message plans. Seems like a pretty easy decision for me. Am I missing something?
