HELP with iPhone 3G AND 10.5.6

Hi everyone, I need your help with my iphone. I been trying to jailbreak it but unfortunately I can't, I get stuck with a white screen right after I release the home button. I tried using the usb hub and keyboard's USB because I did the mistake to update to the 10.5.6 and now I cant jailbreak my iphone 3G. I want to now if I can go back to the 10.5.5 version, I did a backup using time machine before I updated to 10.5.6. and I would like you guys to guide me in how to revert to 10.5.5, or guide me in how to jailbreak my iphone using 10.5.6. I will appreciate any type of help.

P.S I apologize for my writing and I didn't do the kext solution because I am new with MACS and don't know how to use the terminals.
P.S I used quickpwn for the 2.2 jailbreak on osx 3 different times but still get the white screen.

thanks you guys and Merry Christmas to everyone.

It might be somewhat drastic, but you could always do a Archive/Reinstall of OSX and not update to 10.5.6.

But isn't there a way for me to go back to previous version using time machine. That what I want to do I guess, so do I can jailbreak it with the 10.5.5h
