I've received the same emails (for Yahoo email, AT&T email hosted by Yahoo, and Bellsouth email hosted by Yahoo). So far as I can tell, what triggered these notices is a record of accessing the Yahoo email servers via BlackBerry or BlackBerry device. And it is just a thing with Yahoo email. (My mobile carrier is T-Mobile.)
As far as the OP, if it were me and I could live without the text messages from the web services that are not being received, or if there is a workaround, I think I would try and avoid reloading the OS. I guess it would depend what and how much data is on the BlackBerry and only on the BlackBerry. But on the other hand, not being able to backup and restore is a disaster waiting to happen, and should be mitigated ASAP.
