Garmin working on its own ANT+ adapter
Garmin looks to be working on its own ANT+ adapter for the iPhone, as evidenced by a recent FCC filing. There are no technical details revealed, though it's likely to pair and deliver fitness information to iPhones or iPod touch devices with the help of a free app.
ANT+ technology allows wireless transfer of information from devices such as cycling computers, hear rate monitors and other sensors. The GPS data, such as distance and elevation changes, can also be sent, but the iPhone already has this capability built-in. [via Engadget]
