Hello, I originally unlocked my iPhone with ZiPhone. Now I no longer want it to be jail broken. I just want a sim unlock 2.0 and would like to use the iPhone as any legitimate user would. I downloaded the Pwnage Tool, and the bootloaders, can someone write me the instructions to only unlock, I want nothing else, I also don't want the pineapple sign at startup, I would like to keep the Apple logo. thanks!
