Is there an easy way to do this without "jail breaking"? I downloaded the ipsw file and opened it with sn0wbreeze, chose preserve baseband only, and now I have the custom ipsw on my desktop. Can I just plug my phone into iTunes, and shift-click/alt-click update and choose that and have it work? It says it will update and verify with apple, I'm just worried that I might mess it up. I already almost messed up my phone earlier today when I got it stuck in recovery mode so I want to be extra careful, I can't live without a phone abroad.
