Is there a way to go back to a previous version of iTunes?

[thermal]

I updated iTunes today (9.2.1), and now my unlocked iPhone 3G no longer works.

Is there a way to go back to the previous version of iTunes?

Thank you very kindly.

Just use the newest version of Spirit JB, it's 9.2.1 safe. (Assuming you're on 3.1.3 or lower)

You could go to another version but youd have to uninstall, then dig through system files and erase any trace of it.
