Don't listen to that annoying Jennifer Zhang. She just wants a iPhone 4S and so she's saying bad stuff about the iPhone 5. Here are some great advantages.
1. It adds a much lighter, thinner case.
2. Boosts its 4G LTE service dramatically.
3. Better cameras.
4. Much faster in graphics and core performance.
5. Besides, it's only like 1/4 an inch more than the lower generations.
6. Its thinner so the total area is about the same.
7. In the iPhone 4/4S, the play menu in music sometimes freezes or hides or changes spots, and the iPhone 5's play menu is always visible.
8. Triple Power Cores.

10. Faster Web pages and better games compatible for only iPhone 5.
