Edit: For those who keep posting and mocking the ugliness of my solution; At this point in my life I drive an M5 and a new Z4. I think I'm beyond the need to flash a good looking phone to have a feeling of status. I just need a functional phone for when I'm in the field. . . and my post was geared for those needing the same.
Just in case someone needs a solution as I did, I'm sharing a solution that has for the most part solved an issue I was having w/ my TP2. My TP2 kept slipping in my grip, and I haven't yet found a product on the market to remedy this. I found an IPhone case that has helped. It doesn't allow the keyboard to slide or the camera to shoot, but it keeps the darn thing from slipping from my fingers. You can poke a hole in it for the camera and speaker. It's easy to remove for when you need the keyboard. It looks OK, but not too stupid. It's the Jam Jacket by DLO. It is reinforced around the edges and allows the phone to be more pocket able. Hope this helps some out there who might have the same issues I was having.
