Hello everyone, Verizon screwed me over for the last time and now are charging me for texts that should be included in my plan, I tried to explain to the person in billing and they said we will call you back, but guess what they never did So I am thinking about going to T-mobile because they have unlimited everything for 50 bucks. My question is my brother is overseas in the military and contacts me only using imessage because it is free and regular texts are quite expensive. For this reason I would like to get an unlocked iphone 3gs (for now) or an iphone 4 (if I can find one for a good price). My question is are there any issues when using an unlocked phone? Are there any features that do not work properly? Any advice and input is always greatly appreciated.
