[1.1.4][HowTo] Prepare phone to go legitimate on 2.0fw
I'm in the UK and have just bought an unlocked, jailbroken iPhone 2G from Ebay.
Works absolutely fine with my existing SIM on 1.1.4, but I'd like to restore the phone to factory settings and do a legal upgrade to 2.0, then activate it properly and run it on an o2 PAYG tarrif. Syncing it with Exchange is pretty crucial for me - that's why.
But... I don't want to brick the thing.
So, what I want to know is whether it's possible to do this or not. I've read something similar on this thread http://hackint0sh.org/forum/showthread.php?t=45448 that indicates it is possible, but what's super confusing/worrying me is talk about Bootneuter (which is installed on the phone) baseband restores and flashes, and pretty much everything else that indicates how easy it is to brick the phone.
Can I just hook it up to the latest iTunes and upgrade the phone to 2.0 then activate it legally, or do i need to do something with Bootneuter first? Flash the baseband? Base the flashband? Uninstall Bootneuter? Do something to the bootloader? What???
I am fairly competant with this stuff, but am completely new to the iPhone. What would be fantastic is if someone with a bit of experience in all this could post an easy-to-follow step by step guide on what you need to do to get your phone back to it's original state after it's been jailbroken/unlocked. What do you need to check? What version of the baseband do you need to have, etc, etc. There's plenty of tutorials on jailbreaking the phone, but not much info when it comes to actually restoring it!
I have searched through the fourm, and I apologise for the basic questions, but you gotta agree that some of this stuff isn't exactly crystal clear to a lot of people!!!
Thanks in advance.
