Upgrading 2g jailbroke/unlocked from 3.0 to 3.1.2 on Windows

[veamon]

What is the proper method for this? I've been searching the forums, and it seems like there is no definite answer.

I know I can download blackrain to unlock and then download bootneuter apparently, but from what I read, I would have to use bootneuter everytime I reboot the phone?

Does anyone have a a working step-by-step that they've actually done?

Also, I found this method, has anyone tried it?

im pretty sure all you have to do is complete update to 3.1.2, use blackrain, install cydia, and install bootneuter.

I was actually able to do it using the link I posted, just make sure you run aptbackup before to keep your cydia apps. No need for bootneuter.

yeah 2g's are hardware unlocked... once unlocked you never need to run bootneuter again
