Samsung U350 Smooth Holster OEM Holster
The holster is apparently made by some other company for Samsung. But the holster fits the Samsung Smooth phone perfectly. It holds the phone snugly, and the phone is easily removed just by pushing on the clip. I had to run a couple of times with the phone on the holster, and the phone didn't fall off. Best thing is it's not that expensive, but provides a lot of convenience.
