Hong Kong exporter Brando has begun shipping one of the first Bluetooth adapters compatible with the iPhone 3G. The Infinxx AP23 is meant to cope with the absence of stereo Bluetooth on iPhones, by converting USB output to A2DP. The adapter plugs directly into a phone's dock connector, and does not require any removable batteries as it consumes power from the phone itself.

Users can additionally rely on the adapter as a bridge for AVRCP, enabling remote control of play, volume and track skipping functions. The AP23 costs $62; aside from iPhones, it can be used with all Nanos and Minis, as well as full-sized iPods with a color screen.
