Had this last week, and its back. Just checked and got the same code, i think after a while it wasn't there when i decided to check again. Haven't bothered soft re setting personally, i don't think it indicates anything exciting (would love to be wrong) must be some issue with the servers perhaps?
Im still getting the same error, even after the reset. It will tell me my phone is uptodate, then when i check ten mins later I get the error code. It seems sporadic!
