Phone will return to activation screen, but don't panic, just wait. iPhone should automatically restart after almost a minute. When the phone starts again, it should no longer say Slide to emergency, but rather Slide to Unlock. This means it was successful!

I've had a few reports of the emergency slider not changing to the unlock slider. The best suggestion so far has been to keep the iPhone connected to the computer and make sure its detected in iTunes. Otherwise it seems to work if you retry installing AppSnapp till it works. Don't know what the issue is exactly (maybe a server load issue) but if it doesn't work immediately then try again.


DOWNGRADE THE BASEBAND
At this point if you have a 4.6 Bootloader iPhone you cannot continue any further. You can stay at 1.1.1 or you can install OktoPrep and update to 1.1.2 then 1.1.3.

D - February 9, 2008 at 12:44pm
Solved! This was the solution, both the iTunes and independance error :) I fixed this by going to /System/Library/PrivateFrameworks/ and deleting the MobileDevice.framework folder. Make sure you securly empty the trash. Then reinstall iTunes 7.5. It will work perfectly now. from: http://www.modmyifone.com/forums/showthread.php?p=158438
