Update jailbroken iPhone to 2.2

[abramson1111]

I have a jailbroken 2G AT&T iPhone and want to update it to 2.2. I have pwnage tool, and I know how to use it, but I can't find all the frameworks & bootloaders, etc. needed to create the custom ipsw. Anyone got any download links?
Thanks all!

So, I have a jailbroken iPhone running 2.1. I don't need to unlock it to use it on another carrier, I'm happy with AT&T. I don't want to lose all my jailbroken apps/mods/skins/themes/whatever when I upgrade to 2.2.

Is it possible to update a jailbroken iPhone to 2.2 without having to do a fresh jailbreak and losing all of my jailbroken stuff?

EDIT: Oh, I'm running 10.5.6. I heard there is an issue with jailbreaking with this version. Has that been fixed?
