I went to try out a few belt cases and found that a case labeled as for an HTC EVO has just the right length for an iPhone 4 with a bumper, with room left for a credit card and some cash on the side.
Doesn't look as nice as the belt case for my 3GS that I got at the Apple store, but will do until I can find something more customized for an i4 with bumper.
