I wasn't planning to upgrade my 4S until Apple drops iOS support, but I'm moving to a neighborhood with *terrible* reception. The 4S functions somewhat OK on Verizon's network, but the other carriers have very spotty reception. I'm tired of paying a small fortune to Verizon and would love to switch to T-mobile. Apple's marketing for the 6 states, "iPhone 6 has up to 20 LTE bands. That’s seven more than iPhone 5s — which already had more than any other smartphone. That means iPhone users can connect to more high-speed LTE networks in more places. And when you’re traveling, more LTE bands help you benefit from the growing number of roaming agreements around the world." Would that provide enough of an improvement that I can switch to T-mobile? UPDATE: Decided to just stick with Verizon. My brother has T-mobile and is constantly dealing with dropped calls. I would have preferred getting a 5S because of the size, but the price is better for the 6 once you factor in the trade-in rebate. Hopefully I like.
