I appologize if this has been answered. I did a search but did not find anything (I sometimes have a problem using the correct keywords.. )

Anyway, I was sitting, attempting to get the latest PRL update (still unsuccessful, but I sent another email to Sprint). While I was reading through the thread on this board I noticed my phone blink the keyboard light 3 times, then go off. It kept doing this. I turned on the phone to take a peak at what might be going on (nothing).. I then noticed that I had an alert (new email) in the upper left hand corner.. I tapped to view the alert and then turned the phone off. The keyboard blinking stopped.. Is this a feature of the 700p (or perhaps earlier)?? If so, how do I disable it??
