Ok so it seems everytime I go to upgrade and re-JB I "just miss" the window and Apple already releases a new FW version before get to upgrade and re-JB and then I have to wait for JB tools for the new version and then I forget about it and then it's just a vicious circle lol. Anyway, I'm just looking for a simple answer here, I have alaunch/day 3GS running FW 3.0 with the PurpleRa1n RC2 JB. And I have a PC with Windows XP Home and do NOT have access to a Mac, so do I have ANY options for upgrading FW and JBing? I'm on AT&T so I don't need an unlock (but preserving the ability to do so would be nice), I just REALLY need to restore and re-JB because my phone is having so many problems right now (it likes to reboot itself into safe mode everytime I install or update an app and safari crashes if I try to view PDFs, etc). I don't wanna give up SBSettings and my paid Cydia apps so I don't just want to upgrade and use the new iOS features (like backgrounding and such). Any help is much appreciated, thanks.
