ProClip is the best. It's peach fuzz protects well as it slides in. It's very solid feeling, and can swivel too. I used one for my Treo and just ordered one for the iphone 3G. Their old one was for the iphone first gen only since it's shaped differnetly. I just got their email saying the new 3G is ready to order now. Here is a copy and paste:
