Okay, here is what I have: Vista Ultimate Laptop, iTunes 8, 8gb iPhone EDGE with 2.0 unlocked and jailbroken. I want to update to 2.1. I downloaded the custom IPSW here, and I want to restore in iTunes to the custom 2.1 firmware. Is there anything else I should do before I restore? *and please don't tell me that I should have searched, because I did. I just want to be absolutley sure that i'm doing everything right and Won't mess anything up.
