A reboot should always be your first port of call for any problems with a BlackBerry, 8/10 times it will fix a problem. No it will not harm the device.
You are running an OS that is later than the new one. My thoughts are that this may be a bug that could have possibly been fixed. The newest is v6.0.0.337 currently, instructions on how to upgrade can be found in the stickies section of the 9800 forum.
