I just got my hands on a used phone, no sim, no service. Jailbreak and unlock went successfully using Pwnagetool. Now, am I able to load the custom IPSW restore file onto a thumb drive, and share them with a Windows Machine so that a coworker can JB their phone? There's no internet at work. She doesn't have QuickPwn or anything on her machine. I don't know if she's updated to 2.2.1. I do have 2.2 and the custom-restore 2.2 and want to just copy those to her Vista machine, then just use iTunes to restore. I'm pretty sure I can get her phone to enter DFU mode without the prompts from a JB tool. Would this work? Should I get her to download the windows version of a Jailbreak tool first, just to be sure? I don't see that need, as I already have the files needed? What's the "best" JB app for Windows? I could always download that and stick it on the thumb drive for her. Thanks! EDIT: The iPhones are both 3G.
