A guy called Igor Skochinsky has released a program for stripping music files bought through iTunes of their Fairplay DRM.
This was done previously by Norwegian Jon Johansen back in 2004 but Apple quickly released a new revision of Fairplay.
This latest attempt is the first in 2 years to successfully remove Fairplay DRM from even the latest revision of iTunes - 6.0.5.
I'm sure Apple will be quick to release an iTunes update with a new revision of Fairplay.
I wonder how many iterations they have pre-developed, based on the assumption that a revision will eventually be compromised.
