Can anyone recommend an inexpensive PDA case with extra pockets for a flash drive, extra battery, etc, a belt clip, and has a magnet-closure. I would prefer vertical, but horizontal would work also. I would also prefer something that is not too bulky. Guess I am asking a lot. Thanks for any suggestions you can provide. (Needs to fit a phone that is 4.6" x 2.5" x 0.5".)
