I bought the D30 as well (I think that was it, it was from the T-Mobile store). I used it for a few days and then realized that I still felt like I might drop my phone, but I don't like hard cases and didn't care about protecting the front too much. I like silicone cases for my devices, and so I found some cheap ones on Amazon. I got a black (and should have gotten a purple as well). About 9 months later I went and bought another black and a neon green (they no longer had the purple available) as well. They can start to slip off the corners a bit if you put them into a tighter pocket etc, but are fine for where I put my phone (in a loose pocket in my purse). I find them just perfect and don't get too much lint on them. Gives a nice grip to your phone and gives basic protection which is all I wanted. The case stays a bit higher above the glass screen (when on it's back) so you can actually put your phone facedown and not have the screen touch your desk etc. Openings for the ports align perfectly, fits good over the buttons. I have had the first black case on it for about 14.5 months now and it is still in great condition, the others I bought as backups. Here is the link for the one I got:
