Hey all, I have AT&T, and I am considering buying the new iPhone unlocked (IF it has enough features to REALLY differentiate it from the 4s I'm currently sporting. With all this talk of a new SIM form factor and LTE, I'm growing concerned that I will not simply be able to pop out my micro-SIM from my 4s, pop it into my new iPhone, and LTE away (I won't have to change my plan, right?!). I'm assuming Apple will, as with the more recent iPhones, offer the new one unlocked for full retail price. How would I go about transferring my number to the new phone? I'd have to ask AT&T if the SIMs were different, huh? So that's two questions: If it's the same form factor (nano-SIM vs. micro-SIM), I can just swap, right? If it's not, even if I buy it unlocked, I'd still have to consult AT&T to get the number moved I suppose?
