Just wondering if someone can assist me in upgrading my iphone to the most recent iOS.
I have an iphone 3GS (model MC133X, Serial number 934****) bought directly from apple (therefore unlocked). I jailbroke it in 2012 and upgraded it from 3.0 to 3.0.1 (7A400). I updated the iOS to 4.2.1 (8C148a) last year (using GreenPois0n). Can someone please tell me if it is possible to upgrade the above to iOS 6 (jailbroken)?
I have downloaded iPhone2,1_6.0_10A403_Restore.ipsw and redsn0w_win_0.9.15b2.
Can someone tell me the difference between "Select IPSW" and "Extras->Even More->Restore" in redsn0w. What should I use for updating and jailbraking my phone?
Restore it to 6.0 in itunes (make a backup first!)
then use redsn0w to tether jailbreak it
then use redsn0w just boot to make cydia show
