I have tryied to unlock a 2g for a friend, i'm not an expert but i've tryied ... so after the iphone 2g was stuck on dfu, i've restored it with latest itunes, I have read on net some posts how to do a jb and after restore 2g with 3.1.3 soft the 2g iphone can't be recognized in dfu mode.
So please read what you have to do : If your iphone 2g is in DFU mode and when you plugg it to pc sounds like it isn't recognized you have to run devmgmt.msc and on USB controllers you will find your iphone, just go on it and click on update drivers, the mgmt will find the drivers and after that your iphone 2g will be recognized , now all you have to do is to fit the correct ipsw with redsn0w.
Best of all guys !
