iPhone 3G restore problem

[Cryptonv]

Ok, I'm really worried about my iPhone at the moment. I jailbroke it, had syncing with iTunes problems and now i want to restore it, but iTunes gives me this stupid error saying "Software for this iPhone is not currently available. Make sure you have the latest version of iTuness and try again." What the hell? Ive got the latest version of iTunes.

Ok, sorry for being a nuisance but PLEASE HELP!! I'm on a two year cap and would like to have a working phone for the next year and a half.

iTunes only crashes when it wants to sync applications onto my iPhone. GREAT! Well the jailbreak is really going to be used well now, isnt it! (that was sarcastic).

ok first restart your computer. then do a DFU restore. Hold the sleep/wake button and home button for 10 seconds and then release the sleep wake button and keep holding the home button for ten more seconds. You should see a plug into itunes logo. Restore your iphone to the original firmware. Make sure your on itunes 8. After you do the restore set up as new iphone. then delete the pwnage or quickpwn tool you used and redownload it. Then rejailbreak it and Good Luck.

Also sync your apps and music after you jailbreak.

Whats a DFU restore?
Maybe you shouldn't have jailbroken your phone.

Do a little search, it helps.
