So I am getting iffed at the app store, and I am considering big time to pwn my iPhone 3G when 2.0.2 comes out. So my questions are: 1. It is reversible right? 2. Can you change the background/format like you could with the first iPhone? 3. Where can you get said background/theme changes? 4. What apps are must haves ^_^ "i know i want to get touchpad pro and band"
