hey guys, just a quick question here. I'm looking to get an iPhone 5 from Sprint this weekend, but I'm contemplating to trade in my 4S for the 5. Would this be worth doing or should I just buy the i5 in full cash? I want the 32GB, but money isn't just laying around here. I love my 4S because it's jailbroken and I have no idea when the 5 will be jailbroken so I would think it'd be a good thing to keep it. Any input from you all?
