I have the Sprint HTC Touch and I've been looking for a slim cover for it too. Right now I'm using the one it came with but it's too bulky, even for a girl who has a purse.
My brothers, who both have the Mogul, told me BoxWave has the best screen protectors, and I saw they have a
silicone case for the Touch phones.
Does that one seem to work for the Sprint HTCs? I wanted to order it, since I want to order a protector too, but for $25, I was cheaping out. Heh.
