So, now that I may be getting some iPhones sooner then initially expected, as we will now switch to VZW. I was looking at Apple's leasing program, and I'm a bit confused. They will charge 32.45 where as ATT and VZW charge about 27 dollars for the same phone. Why would I opt for Apple's. The only advantage I can possibly see is that I get an unlocked phone. In both cases, you need to trade in your old phone - what am I missing?
