Wow, great guide dude.

That new recovery menu looks alot better than the blue one (but thats just damn picky).

Shouldnt you hide all the mac addresses in the pics?
(not sure why, everyone seems to do it though)

**The EX** · July 15th, 2007, 11:58

The people who gave me the pictures don't mind.

Nope, i hate it when people do that! the only way someone can use that is they use your MAC address and get banned from an access point then your PSP cant use that point! but even if that did happen just use MAC cracker and change it!
