iPhone Opens Up Bluetooth For Data

WildNahviss writes "Apple has loosened its tight grip on the iPhone and allowed a third party to develop a health device that exchanges data with the iPhone and their hardware. Is this the start of a trend for Apple that will relax constraints on non-audio Bluetooth use, or is this an exception? Does anyone know of any other devices for the iPhone that allows non-audio Bluetooth transmission of data?" Reader climenole points out an article about another health-sensor system, dubbed a "body area network," that is built to work with Android devices, but not via Bluetooth.
