The BlackBerry site doesn't exactly make the demo of the new 8800 easy to find.
So I've decided to dive in and find it for you.
You're looking at a screencap of the BlackBerry 8800 demo landing page. Each of the categories listed on the left offers several views.
The text accompanying each view is what we geeks sometimes have referred to as a "guided setup." If you are new to BlackBerry 8800- or even new to BlackBerry- and learn better via visual prompts than by "first you, then you" user manual text, I recommend that you prepare your new BlackBerry device via this demo.
Then, if you have questions, that would be time for the User Guide. Which, in the case of the BlackBerry 8800, you would find here.
