The iPhone is out. Letting the big-boys do the iPhone coverage I thought to chime in with something a little less mainstream. Apple released a “Works With iPhone” badge, mark, logo, whatever you want to call it.
Viewing the accessories page Apple has the following USB related accessories for the iPhone:
USB Power Adapter
Apple Dock Connector to USB Cable
iPhone Bluetooth Travel Cable
Apple USB Power Adapter
iPhone Dual Dock
Other iPhone accessories include Bluetooth connectivity, headsets, AirPort Extreme support and fancy TTY adapter. Given you just dropped at least 4 bills on the iPhone I’d sport the little extra cash for certified accessories products, but that’s just me.
