Can 1.1.3 OTB (week 3) be downgraded to 1.1.2 to work with TurboSIM?

**Kraut55** · 02-07-2008 12:48 AM

I am not that interested (yet) to have 1.1.3 on my iPhone but would be happy to have a working 1.1.2 iPhone. The instructions for 1.1.2 OTB require the usual (restore to 1.1.1 etc.).
Would it be possible to use the same procedure with an 1.1.3 4.6 OTB - downgrade to 1.1.1, install oktoprep, update with iTunes to 1.1.2, run jailbreak.gar, install iworld and use the TurboSIM or is that not possible?
Thanks.

Everything like you wrote except Turbosim. New baseband don't work with any tipe of proxy sims, yet!

Are you sure? I was under the impression 1.1.3OTB wasn't jailbreakable... at any version.

and it isnt. thats why you will have to restore to 1.1.1 first, THEN jailbreak.........

back to 1.1.3 you will be able to use it as an ipod, no more, no less.

A friend of me has a 1.1.3OTB, bootloader 4.6, modemfirmware 04.02.12G.
Downgrading to 1.1.1 and then al the way to 1.1.3.
Will that be possible with xsim?
