Hey Everyone! I would appreciate any and all advice about what I should do regarding buying an iPhone 4s. The story is quite complicated so here goes. I bought an iPhone 4 in August of 2010 with AT&T under a 2 year contract. I then got that iPhone stolen in Brussels in June of this year (in a ridiculous turn of events that I shall not elaborate on). I was out of the country until mid August and at that point made the decision to wait and see what Apple would come up with knowing that I would have to pay an early upgrade price anyway. I now somewhat regret that decision (someone told me the "S" stands for "Sucker") since I've been using a Nokia brick phone ever since. My options now are as follows. Pay early upgrade which for 16 gig (what I want) is 450. Buy an unlocked iPhone 4s and use that to run out the rest of my contract. price there is 650. Make use of the fact that my Mother has a 3GS and is eligible for a full upgrade now so 200 for new iPhone 4S. But the question here is if she buys that under her phone number would I be able to do sim card switch and use that iPhone 4S with my number and she use the 3GS with hers? We are on a family plan together. This all gets complicated by the fact that I might spend the entire 2012-2013 academic year (or half of it) abroad (I'm a college student). In tha case having an unlocked phone really makes sense to me but I am of course very very weary of paying 650 plus tax on a phone.... Well any thoughts are much appreciated! Are there any options I might have missed?
