I'm real nervous about it slipping out. Does it sit in the holster firmly?

Yes - quite firmly. I had one for my 6700 and it never came out of the holster.

Be careful, though, of the kind of belt you use. If the belt is too thick, and/or you have a "spare tire" around your middle, the holster can slip off the belt. I had that happen a couple of times with my 6700. Though I think they did some re-design for the Titan, so perhaps less risk.

thank you all that provided reviews. was on the fence, but now I think I'll pick one up. one more thing. the leather holster had a tendency to press buttons - causing it to dial out. how well are the buttons protected - particularly the phone buttons? have you experienced it dialing out in the holster unintentionally?

Is it possible to have the phone screen facing the other way so that it's facing outside?

Yes, Although that kinda defeats the purpose of the felt lining on the inside which was placed there specifically to protect the screen, also one rogue corner and your phone's LCD is toast...

The holster holds very nicely and firm. I never feel that is going to fall out. I used to have something similar when I had a Blackberry but this holster is 10 times better. The other question about turning the phone around and have the screen face outward. It does fit that way but I wouldn't do that. I would scratch the screen up. I have used it for over a week now and I think it is great. I normally don't post much I just come here to find out how to find tips and tricks but I thought this product was worth posting.
