Downgrade 3G 5.13.04 on 4.0.2 to 3.1.x
My 3G is unlocked and JB via Redsn0w and blacksn0w. It ran bad before the sn0w mods and I want to downgrade to 3.1.x. How do I go about doing this? As I understand- 3G only needs SHSH for 4.0 and higher - you have no restrictions on restoring to iOS 3.x?
I don't have easy access to a Mac so PC method is only likely solution.
BTW did Apple ever fix the bugs on OS4 with the 3G? I'm guessing they did, but it cant be unlocked or jailbroken.
