Help - My Bb Has Stopped Showing Mms/text Sender's Name????

[JoJo2006]

My BB has suddenly stopped displaying the name of text message senders, it now only shows their tel number. Caller ID is working fine. I'm sure it's something I did because I was "playing" with the settings yesterday....now I can't figure out how to get it to show the names again!!! All help very much appreciated...Thank you.

Dont worry, mine has been doing the same thing, especially around 12am midnight on new years eve... All of the responses i get, it just shows the number of the person in the BODY field, not the FROM field - that is empty. I think Nextel is having a problem again.
