After much deliberation I've decided to just wait until Friday to buy my iPhone 3G's case. I'll shop around at the Apple Store and hopefully they'll have something suitable. Even though it seems that all of the online stores are offering 30 day guarantees I'd rather not deal with the hassle of sending something back if I decide I don't like it. I'm going to have to baby my iPhone if they don't have anything in the store that will work.
I just want something that will protect the phone and hold it on my belt securely. The Sena cases are lousy in my opinion. I had one for my Treo and it left the corners completely exposed. Absolutely useless for drop protection (which is the primary reason I want a case). The Griffin Wave looks nice, so does the iSkin Revo, but I need it to be on my belt. Maybe paired with a side pouch kind of a thing, but I don't know if those will handle the phone when its already in another case. Sigh.
