Putting aside the fact that I can sell my old iPhone4 AFTER i get the iPhone5....... would this strategy work. Someone offered me $200 for my black i4 with a shattered back glass. I figure this is pretty good and will pay for the i5. Now should I sell it now, buy another i4 ( at ATT) to use until next week and return it to the store and get the i5 on launch day (assuming I camp/they have it in stock). I guess what I am asking is will this work?
