1) Go into the phone app, choose the menu and choose options, call logging, then set to none.
2) I bought one from the mall that is a leather pouch without the magnet... Check Vaja Cases, www.vaja.com, they are sweet. I have an extra one I dont use cuz its so expensive I dont want to mess it up.
3) Jivetalk is what you need, as mentioned, but you really should email the developer to ask for it, since its specially signed for your BB.
