Some time after though, users reported they weren't able to update to this new OS and many wondered what had happened.
In a statement regarding the missing update, RIM responded:
"RIM discovered an issue with the PlayBook software 220.127.116.118 update. The update has been removed. Customers that have already successfully updated to version 18.104.22.1688 are not affected and can continue using their PlayBook with the updated software."
The update didn't really bring anything new to the table for PlayBook users so those that weren't able to update aren't really missing anything. Hopefully they can just get 2.1 ready and send us that update soon instead.
