I see a lot of different guides for jailbreaking the 3G iphone running 2.0 software using Windows. My question is two fold.

1)Which guide do you guys suggest using? I looked at the one at sleepers.net but I'm not sure if there are better ones. Does anybody have some links of ones they've used and found easy?

2)When winpwn comes out for 2.0.1 firmware will the upgrading process change? or should it follow the same steps as the 2.0? So basically, can I follow the 2.0 guide for jailbreaking the 2.0.1 firmware?

I appreciate any help I can get as I'm completely new to all things iPhone!
