I learned most by just playing around with my first BB, but did actually read some stuff in the manuals, learned some stuff in these forums and learned a lot of pretty good stuff reading the BlackBerry 101 right here on CrackBerry.com.
This is my 3rd BB. I just didn't have this problem before.
Do you know of a good place to find keyboard shortcuts?
I found a really good theme for the 9630 that will work on the 9650 that has great keyboard shortcuts, but I deleted it by accident recently and have not searched to reload it. And again, these forums and CB's BlackBerry 101 has lots of great information. I am also on my 3rd personal BB and we have several others at my company that I get to experiment with occasionally when my employees aren't looking or leave them laying around.
