So, I've been on a tracphone for a few years now, and I've decided that I'm sick of it and ready to adopt an expensive 2 year contract for the sake of internet everywhere I go. I think I've already worked out that I want an iPhone 4S, but if you can make a compelling argument for a different phone, go ahead. So I guess what I'm really wondering is, which carrier can provide the best service at the best price? I'm military, so I'll be out of the country for sure. Also I'll be stationed in Montana, and from all the coverage maps I've looked at, there's not a lot of great technology happening there, which is why I'm interested in a 4S even though it's an older phone. Also another thing I was really curious about is if it's currently viable to replace an internet ISP with cell phone tethering and a kick ass data plan. It looks like the max that at&t offers is 5 gigs a month, which is very low by PC standards. Verizon goes a bit higher to 12 gigs, but that is also on the low end. Are there all in one deals out there that combine cell phone with ISP?
