iPhone 3G Downgrade to 3.0 from 3.1 doesn't work

Been having repeated issues with downgrading from 3.1 to 3.0 on a 3G iPhone.

I can follow the ihackintosh guide to go back to 3.0 only until the point where the 1015 error shows. Then as the guide says, i run the redsnow program and use the 3.0 restore file.

Unfortunately when redsnow is finished and the iPhone is done with the 'jailbreak' the screen will not move from the 'plug into iTunes' screen. Phone turned on and off and the screen still shows the same.

Is it that Apple has now stopped signing the software? Not particularly worried anymore as i'll keep 3.1 and just wait till dev-team get a hack up and running. Pain in the arse i tell thee!

Sand Springs,Ok
use quickpawn

once you get i-tunes error code,close i-tunes,open quickpawn
follow directions,i-tunes will open showing 3.0 firmware,close quickpawn
you will have to set up as new phone through i-tunes,then jailbreak with redsnow 0.8
all is good,mine works fine
