I have been using the Yamaha MD-BT01 Bluetooth Wireless MIDI Interface. It is basically 2 MIDI plugs (In/Out) connected by a short wire. It is powered from the MIDI interface itself and send midi data to the iPad or iPhone synths. It does however cost a bit more than the USB solution above. $45-50.
