Hey i just got an original iphone today and now i am trying to unlock it using winpwn. Evrything goes fine untill i get the the part where it searches for the BL-39.bin.. i have no clue what this is or how to fix it.. please help if you know what the problem is i would really like to use my iPhone

If it is the iPhone 3G you are trying to unlock stop trying, you aren't going to get it. As of now the 3G is unlockable. As for the 1st generation pwn it and get BootNeuter on it and unlock it.

Place BL-39.bin (http://www.4shared.com/file/60444947/833f935b/BL-39.html) on your desktop and try again.
