The Mogo Talk Bluetooth headset/case just got updated for iPhone 4, which is great, since the iPhone could use both protection and a wireless communications device. But it seems they didn't listen to any of my suggestions.
My complaints from the original said that I wanted one integrated charging system - this still has a microUSB connector - and a built-in battery pack. It's just an updated version of the old device, priced down to $US100 from $US130. If they had only made the case both a battery pack as well as just a case/holder for the headset, it'd be a clear buy. [ID8Mobile]
