Hi all

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?

Much appreciated

Thank you.

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

Hi theiphoneguy

Thanks for your reply.

Just to further clarify.

1- Should I not use the ipsw that I have just downloaded?? My iphone is jailbroken. Updating it via itunes won't mess it up??

2- Tether jailbreak ?? I just read this on redsnOw's official website "For the 3GS however, the jailbreak is untethered and there is no need to connect it with your computer for every reboot."

you can use that one. shift+click restore and point itunes to it. untethered if those digits you said are the 3rd, 4th, and 5th digits yes
