Jailbreaking the iPhone 3G with blackra1n
I have both a 3GS and 3G and jailbreaking the 3GS with blackra1n went by without a hitch. However, the iPhone 3G, as others have discovered, does not go through as smoothly. I have tried, like others, a million times to jailbreak my 3G with blackra1n but could not get past the iTunes recovery screen.
Well on the 1 X 10^6 + 1 time I finally got this thing to go through and here is the setup:
I am using Windows 7 RC1.
1. Leave iTunes open.
2. Disable automatic syncing in iTunes.
3. Set blackra1n's properties to run in Windows XP service pack 3 compatibility mode.
4. Set blackra1n's properties to run as an Administrator.
5. Now make it ra1n.
This was successful for me and I hope this setup solves the problems others were having.
