I'm not sure how you are gripping it to pull it out, but I hold my thumb on the belt clip to hold it down, then use the rest of my fingers to push the BB toward my body and up out of the holster at the same time. I didn't figure it out at first, but after the first time I tried that, now I do it all the time and it's very natural.
There's a big Bluetooth icon on the main screen, when you select it with the wheel it says either 'turn bluetooth on' or 'turn bluetooth off', depending on its current state.
The 'web' button can be re-configured. I have mine set to 'keyboard lock'.
It would be nice to just start typing a name from the main menu. You can configure the 'web' button to pull up the phonebook and then just start typing . I think this would be the same as using the green 'phone' key. I just go to the phonebook icon.
