I'm currently an AT&T customer in the NYC area using the iPhone 4 and very happy with their service. Recently, I've been looking at Verizon solely due to the fact that they have LTE available in the city where AT&T is still on pretty slow 3G (around here it's less than 2 MB/s). That being said, I'm heavily committed to iOS after the amount of money I've invested in apps and I also believe it is the best mobile OS on the market which is why I'm reluctant to switch at this time. Recent rumors have suggested that the iPhone 5 could include LTE which will put me in a tough situation. The only LTE plans that AT&T has announced so far is their initial markets (Chicago, Atlanta, Dallas, Houston & San Antonio) and no word about NYC at all. To me, it's worth paying the early termination fee (I'll be about 14 months into my contract in October) and switching to Verizon at that point. Their LTE speeds in NYC are incredible and would be a major advantage over the AT&T iPhone that can only connect to the 4G network is VERY few locations. Anyone else in the same boat?
