Should I buy a iPhone 4s or 5?

I'm not sure at all which one I should buy. I know the iPhone 5 has better performance but I just wanna make sure I'm getting the better deal. On the iPhone 5 I'm worrying about the app problem where some apps aren't updated to fit the screen. I feel like it's gonna bother me. Everyone seems to have the iPhone 4s. If you have the iPhone 5 please let me know what you're thoughts are. I've done so much research and reviews on the iPhone 5 vs the 4s but I don't know what's best for me, I'm still VERY hesitant. I don't really consider buying any other phone so keep that in mind. I would prefer the iPhone WITHOUT the contract but it's costly even with a contract so I think I'm gonna have to go with the contract.

Added (1). By the way. Does anyone know how much the contract costs?

DO NOT DOUBT. GO FOR THE 5. I HAVE ONE. IT IS FAST EASY TO USE VERY THIN YOU WILL BE So HAPPY WITH IT. GO FOR IT

If you just want no contract phone, get an iPod touch, it has all the same capabilities but is cheaper, if you needa phone ho with the 5, it's longer and thinner with better everything, i haven't seen any problems with apps.

Unless your an extreme technology geek, I don't think you'll tell much of a difference, so I suggest 4s maybe? But later on your really gonna regret getting a 4s, cuz all apps will start being made toward 5. Apple always has odd prices that change, and products that change all the time, it's your call.
