Jailbreaking 2.1 iPhone 2G

[davidi]

Hey, this is my first post on here... Whats up?

So I need some help from the geniuses around here.

I have a 2G iPhone, totally jailbroken, appstore working fine, and so on. Thing is, I didn't jailbreak or unlock it myself, I had it done at a big tech/hacking mall in Bangkok, so I don't know how to jailbreak to 2.2.1 or whatever the newest available version is.

I know about QuickPwn, and I've read the tutorial and everything, but that seems to assume that you have a locked, never before jailbroken iPhone. So does anyone know what I should do? Just press Restore like the iClarified guide says? Or...?

I know it's easy, but its important. Don't want to brick my iPhone or something.

Another thing is, my iPhone is running SUPER laggy and slow. Really annoying. Takes 10-15 seconds to load the camera and such.

So yeah, any help would be appreciated!

Thanks,
David

Edit: I have an aluminum Macbook, 2.4GHz, 250GB HD.

I would probably just restore iit with the original firmware from apple and then just jailbreak and unlock it with the pwnage tool ...
