I've successfully activated and jailbreaked (or is it jailbroke) an UK phone by downgrading the firmware to 1.1.1 and then following the various procedures as outline on many posts on here. No problems ecountered. Yippee!

Has anyone ever taken the step to upgrade the firmware to 1.1.2 again, while keeping the phone activated and jailbreaked? Couldn't find anything about it in any posts...

hallo i had the same thing (downgrade from 1.1.2. to 1.1.1) now my iphone tell me activate. Now what i have to do for unlocking? please tell me.

thanks

Hey Dude

Ok, I need some help, can you help?

I have a UK iPhone and am running iTunes 7.5 on OS X Leopard. Now I restore the Firmware to 1.1.1 but I still have the phone on the connect to iTunes screen.

How do I get rid of it and move on to activate the phone?

Would be cool if you could write a tutorial on how you did this. from step 1.

Thanks Dude

Friends, the activation and jailbreaking process on 1.1.1 is WELL document in great detail in numerous posts on here, even in stickies. Tutorial galore. It doesn't take much searching!

You can downgrade, oktoprep and upgrade back.
Jailbreak under 1.1.2 and activate by replacing lockdownd.

Now, since the baseband bootloader on the OOTB 1.1.2 is different, you are stuck with the new firmware (no way to downgrade it) nor can you run anySIM against it, as the read/write utilities for the baseband wil not work.

The best you can have at this time is a jailbroken iPod touch with mail capabilities.

Be patient, that soon the dev team will release a new set of tools to handle the new bootloader.

Remember that this apply to all new phones, so there is a reason for getting there. It will just take time.

Oh I'm not only patient and happy to wait until an unlock becomes available, but very happy already and in awe how the geniuses managed to get this far in the first place! So here's a big THANK YOU to everybody!

So with my downgraded to 1.1.1 UK phone, it behaves no differently than an activated and jailbroke US phone, with the exception that it can't be unlocked? In other words, the upgrade instructions to 1.1.2 as described in various posts (but in relation to US phones) would be the same for me?
