When I briefly had an iPhone 4, the case I liked best was Belkin Grip Vue. I think it's that TPU material - which has grip like silicone but doesn't collect lint as badly, looks much sleeker and glossier, and slips in the pocket easier. Best Buy had 'em for $20 but they were clear only, which actually gave a translucent white effect which I didn't like. So instead I found a dark smoky one on ebay for a little over $10 and iPhone 4 looked great with it. But this wasn't a holster setup. I prefer to carry my phone in my pocket so it was perfect for me.

The Jawbone Icon models look really good, and I liked that they used a standard microUSB plus had a physical sliding on/off switch. What I didn't like was the lack of volume control. They claimed their advanced sensors would automatically adjust volume correctly but I prefer having manual controls. I've always leaned towards the Moto headsets with the flip out mic. Easy to shut off and easy to tell at a glance whether it's on or off. Like the H17
