How do I update from JB 2.2 to 3.0?

[ThugZilla]

I have a question. If I want to update from JB 2.2 to 3.0, do I first restore to factory 2.2, then update to 3.0 and jailbreak? Can anyone give me a step by step guide of what to do? I read somewhere that I will lose the space my jb apps took up, how can I prevent this?

Just update to 3.0 thru itunes.
Then jailbreak with Redsnow or PwnageTool

Rather than update, which will lose your JBed space, restore with 3.0, which will give you a stock phone to JB and re-sync your info to.

What do you mean by restore through 3.0?
