iPhone case with strap - the sort that doesn't need taking the phone out to use

Hi everyone!! So, I finally have my iphone! Man, I'm so happy!

I just need to find a case for it. Now there are lots of really nice ones out there, but I'm specifically looking for something that will have a strap attached, because on days when I'm wearing a skirt, I usually don't have any pockets for it to live while I'm using to listen to music, and simply holding it in my hand makes it too easy to drop if someone bumps into me in the bus or whatever It doesn't have to have an actual fixed strap; all I need is a little loop I can use for a keyring or one of those cellphone wrist straps. For the same reason, ideally it would be the kind that let you use the phone without removing it from the case, or you're back to square one when you actually need to use the controls!

I don't really have a tight budget on this, although I don't think I'd pay for one of those swarovski ones that cost several dozen lol, but then again I don't like the look of those, so that could be why I don't find them worth the money

So anyway, I would love to see everyone's favorites!
