Lets clear some things to avoid further FUD:
1. Psfreedom 0.5 works with stock kernel and power-kernel 40
2. Psfreedom 0.6 works with stock kernel and power-kernel 46
a. new options JIG (downgrading) which according to multiple sources will break blu-ray playback.
b: optimizations in the psfreedom application according to post:
http://talk.maemo.org/showpost.php?p...&postcount=715

Some advices:
Don`t downgrade for now from 3.50 to 3.41 ! There are rumors for hacked 3.50, patiance is a virtue.

Both of the payloads available in the Psfreedom are working. If you have issues post every step in details as this will allow us to help you.

Easy way to check if the pl3 payload is loaded start the application, jailbraik, led indicator becames red and type in the terminal (with root):
lsmod |grep psfree

if there is no output you are using the wrong psfreedom version for your kernel.
