The sidekick had a nifty setting, so that for every 2 or 5 minutes you went with an unread text, email, etc. (anything that would have a little alert icon) it would give you a little vibrate to remind you something is there...
Does blackberry have this too? I can't seem to find a setting like that anywhere
There's no specific setting that will do it, us BB users love our LED. However, there is an app called BerryBuzz that may do it. Someone will come along and let you know.
