I have a Samsung Galaxy Ace II X on a 2 year contract. I've kept it in good shape but however I dropped it the other day and the screen dropped and is now unresponsive. I'm only halfway through the contract however, and I think I have around 120 on my tab. I don't want to get it repaired. Could I potentially get a new phone, such as a iPhone 5s on the same contract I have right now? Would I be able to use my tab?
