Here's the full story. On a family plan with 5 lines. I have an iPhone 4 (used my dads upgrade to get it). My line is now eligible for an upgrade which would put all 5 lines on contract. The next available upgrade comes in Feb then another one follows in May. My parents don't upgrade often like most parents so it works out pretty well for me who likes to upgrade often. My mom is hurting for a new phone but just wants a simple non-smartphone and I don't want to use one of the upgrades (or mine) to get her a phone since it's not worth it for a cheaper phone. So, now I am debating whether or not to upgrade my iPhone 4 to an iPhone 4S and sell my iPhone 4 on eBay for ~340. If a iPhone 5 happens to come out in June or Oct of 2012, I would still be able to get that one, using one of the other lines. I have been going back and forth trying to figure out what the best plan is but maybe you guys can help. I have to admit I am an apple fanboy and I would love this new iPhone but still debating whether or not my 4 would suffice. I am torn
