Blackberry makes a nice Charging pod for the 9700. I like it as I don't have to plug anything into the USB port. I just drop the phone into the pod. Small and light enough I take it on trips with me as well. Do a search on Amazon for 9700 Charing Pod and you will find a number of vendors that are cheaper than the BlackBerry Suggested price of $39.
For cases, I am very partial to
Rim BlackBerry Bold 9700 Cases by Beyza Cases | Leather PDA Cases, Smartphone Cases, iPod Cases, iPhone Cases | Leather Case and Sleeve . Seems they have taken the slimLINE case for the 9700 I use off the web site. But when I ordered, they were low on stock on all leather types. Should have them back on the site soon. I've used these cases in my pocket for a while now and love them. You can see the slimLINE cases on the link to the 9000. I have heard others saying the 8900 cases work well with the 9700. A bit tight. But they do stretch a little bit.
