I've added lexi comp to my bb pearl. I do not reccomend it!!
The problem with the software is that it needs an active signal to "pull down" data. The data is not stored on the blackberry much to my dismay. As you know, we live in a world of imperfect cell phone signals, which can even be worse in the confines of a hospital...and of course, does your polices permit the signal on the unit.
Lastly, the access is slow! I do not know why they did this with the blackberrys. They have expandable memory, so why not...ask lexi comp.
***I still fall back on my old trusty palm pilot. Bigger screen, faster access. Dependable, rugged, what more can I say.
I still love my bb for handling emails...that is what they are the very best at bar none.
