well since i answered this 3 times this week here go's the last time you will need to do a security wipe to get rid of it options security general no services click wipe type in blackberry to confirm you will need to re-sysnc to get your address back then re setup your programs
Go to >Messages >Options >View Folder >Phone call logs. Highlight the date and click "Delete Prior." do the same for >Missed Call Logs. That should clean out the 1 call. If that still doesn't work then you'll need to follow the instructions above. I suggest upgrading your OS to the latest. That usually takes care of it if the 1 missed call is still stuck there. Also, it will probably prevent it from happening again.
Yes, substitute "click menu key" for "click trackwheel." If you've already tried my suggestion above then you are probably stuck with updating the OS or wiping and reloading the OS. If it's a mised call icon then it's not an SMS. The above poster is wrong.
