PeeKaWho email and SMS notifier

I have been using this simple but nifty software called PeeKaWho from SmrtGuard for almost a month now, and I must say, I like it.  Basically, it is a small applet for the RIM BlackBerry that pops up upon receipt of an email or SMS. There are lots of configurable options, and it has proven useful to me especially since I read a lot of ebooks on my BlackBerry. Being able to deal with an incoming email or SMS sure beats switching over to check--or trying to continue reading but wondering what it was that just came in! Article
