I recently downgraded from 4.2 to 4.0 and jailbroke it/installed Cydia, can I remove the Jailbreak, update to 4.2, and still be able to use Cydia? Edit: So that means I have to stay at 4.0 forever? >_>

Whenever I try to use my 3,E,D, or C keys on my laptop they wont work. It's odd because those are the only buttons that don't work, and there all diagonal to each other. I didn't spill nothing on the laptop...did I press something that locked those buttons? Help!
