Hmm... well I know there is a mail fix for 1.1.4 or earlier... but I don't know if they have fwchanger for 2.0.
So Either you downgrade or wait till they have fwchanger for 2.0.
Hope this helps... and good luck.
did it work when you were in normal 2.0?? mine didn't . so I made a clean restore to 2.0 ( no backup ) and then it worked. So just sync everything before you restore, do a fresh restore (no backup ) and then resync, Should work
