2.5 is gonna come out, i would just wait. im no noob but using iPlus and iLiberty on my 1st gen was so much easier

putting in dfu is rather tricky. i had a problem with it and then my usb screwed up at the sametime so I was stuck in recovery mode for 2 days until i had it rebooted at apple.

if ur gonna try it, watch and read all the tutorials first
