Funny point this morning, the iTunes application on the Apple site is back to version 10.6 (March 7th, 2012) The latest version 10.6.1.7 was released on March 28th ;)
Based on some Apple forums feedbacks, it appears that 10.6.1 is having a lot of bugs (pb of sync, break Apple TV link etc)
Therefore, Soft2base will revert back to 10.6 as well.
EDIT (Apr 24): Apple sounds to have serious cache or web cluster issues as the iTunes download page is constantly moving from 10.6 to 10.6.1 and back. So this last version will be re-integrated soon
