There are a few different "notifications" that would alert you for that. have you checked your Browser for Push messages? And is there anything in your Messages folder at all? You might want to do a "Delete Prior" to make sure.
Can you take a screenshot of your Curve and post it on here?
Ya I'm sure a battery pull might fix it, since if I were to guess it's probably telling me to reset my curve to get the latest updates from my service provider.
But, you know it would be nice to actually know what the icon means.
How come there's no list of all notification icons for the blackberry on the blackberry website. You would think that would be a given wouldn't you think?!?
Did you ever resolve this issue? It looks like I am having a very similar problem, and I can't find a list of notifications tht show what the icons look like either.
I experienced the exact, same problem. I decided to pop the battery and reboot my phone. Same blue icon showed up, without the red star this time. It happened to be my Facebook notification. The red star covers the "F", making it look as though it's an antenna. Hopefully, this helps!
