Hi Everyone - I jailbroke my phone prior to a trip --- but now would like to restore it to original factory condition since it is running a little slow. iTunes wont let me restore the phone (not update, but restore). It says verifying with Apple, and then gives me an error. I used: redsn0w_mac_0.9.6b4 iPhone3,1_4.2.1_8C148_Restore.ipsw How should I restore it? Thank you!
