I have just bought an iPhone 5 and I'm having buyer's remorse. I forgot that the 5S will be coming out in a few months and feel like I should have just waited. Should I take the 5 back and stick it out with my broken (screen cracked and lock button non functional) iphone 4 for a few months? Should I get the iPhone 5 now and just sell it when he 5S comes out? I'm on tmobile if that matters.
