iFaith?

[sigtau150]

has anyone used iFaith on here? If so, can you let me know if this is possible?

1. use iFaith to save current version - iOS 4.3.3, BB 05.16.02
2. use redsn0w to upgrade BB 6.15
3. test GPS
4. if GPS no longer works, use iFaith to restore back to original BB?

Thanks!

iFaith creates a signed ipsw; it doesn't help you downgrade the baseband. Once you're on iPad baseband, there's no going back. Until Apple release a baseband 6.xx. By the way, GPS doesn't work with iPad baseband, and it's mentioned in the warnings all over the tech blogs on the internet.
