Just wanted to try it on my winblows machine and was curious if others were having the same problem.. Well that and Im ditching my Mac Pro and my Macbook Pro.
Now if only they could come out with a JB for my 3GS with OS4!!
Yea ive been doing the same thing. Iphone is jailbroken with 3.1.3 I create sn0wbreeze firmware for iOS 4 and keep getting error 1600 in itunes on restore and dfu mode
iReb doesn't support 3GS and that sucks. Both times ive been upgrading to iOS4 I get 1600 errors so I wanted to provide this solution. this has worked for me twice now and took me hella long to find it the second time, upgrading my 3GS to iOS4 and beating the 1600/1604 errors. It involves removing iTunes but it will keep all of you song and playlist data. Good Luck!
I have had this problem before and what I did was leave iPhone connected to pc and close iTunes with task manager and reopen iTunes and it will start over without any errors. Hope this helps
