I have an iP4, and this next iPhone has to have more than just a new screen and LTE to sell me on it. The problem is that I'm happy with the speed of 3G. Even when I tether to my laptop, the speed is just fine. It's not like I'm downloading huge files from torrents. The next problem is that if it's just a new taller screen, it's just not a huge of a difference to me. I'm sure the processing power will increase, but I can just upgrade to the 4S and call it done. The third problem is that I still have Verizon unlimited data and if I upgrade to a LTE phone when the new iPhone comes out, I'll lose my unlimited data. The iP4/4S will be able to upgrade to iOS6 and have most if not all of the functionality, unless apple restricts new features to the new phone like Siri on the 4S. All in all, the next iPhone will have to have some pretty heavy duty hardware upgrades to sell me on it. How about you?
