So I dropped my iphone on the pavement tonight and cracked the screen. The touch screen is still working perfectly but I think I'm going to have to part with it because the cost of repairing it is a bit ridiculous. Instead I think I'm going to sell it on ebay. I want to know how much it will cost to switch to a more affordable AT&T plan with a basic phone I already have. Will there be a fee considering I had to sign a 2 year contract for the iphone plan?
