Apple is rumoured to be planning a wearable mobile device: the iWatch. Whether it’s an iPhone accessory or a stand-alone mobile phone… or a figment of overactive imaginations… remains to be seen, although press reports suggest it could be launched by the end of 2013.

Last night the Bluetooth Special Interest Group announced the winners of its inaugural Bluetooth Breakthrough Awards competition.

Winner of the Prototype category - and overall winner, chosen from over 300 submissions - was the Tethercell battery adaptor, a product that enables almost any product using AA batteries to be controlled or monitored via Bluetooth.

ABI Research has forecast that Bluetooth Smart - the new low-power Bluetooth v4.0 specification - will drive cumulative Bluetooth-enabled device shipments to 20 billion units by 2017.

The first ten years of Bluetooth availability saw cumulative shipments of Bluetooth-enabled devices reach 5 billion, largely resulting from its use in mobile phones.
