2.2.1 Jailbreak problem

I have a 1st gen ipod touch and have jailed it several times previously (using Quickpwn). However I recently upgraded to 2.2.1 and decided i wanted to jailbreak it once more however now whenever i try it gets stuck on the apple logo and i have to put it into recovery mode. I downgraded it to 2.2 and attempted to jailbreak it that way but that also got me no where.

Any advice/similar experiences would be welcome.
