The first thing is don't make multiple threads we all go through them pretty regularly and it confuses some people and they will post the same thing twice or just skip your thread all together. The next thing is next time don't do things just because you think it will work ask here first and then someone will give you help. What you need to do is look up how to put your phone into DFU mode, and if you do a restore right now you will get iOS 4.3 which you wont be able to JB so you should decide if that is what you want? Are you on Windows or Mac? If you want to still be JB then you can put your phone into DFU mode and restore from a custom 4.2 ipsw made with pwnage tool. So once you've answered some of the questions I'll give you more help based on that.
