How do I go back from 0.8 to 0.6

Hi guys!

after enjoying an unlocked iphone 3g with ultrasn0w 0.6 for a few weeks I made a big mistake by upgrading to ultrasn0w 0.8 via Cydia.

since the upgrade, whenever I go to areas with poor receiption iphone looses signal and dispalys NO SERVICE which stays forever until I switch it off and on or go to airplane mode on and off.

How cat go back to version ultrasn0w 0.6?

you could try finding it on the iPhoneFix.de V2oo9.2 - Largest iPhone related filebase on .NET! No.1 File Source! ftp server, I know there is one that is version 0.6 but its for 3G, and, it only installs under windows......

maybe that helps.......
