Nice! The Watershot for an iPhone now has the Blue Buddy as a companion.....the "finger holes" on the mystery device actually fit over the buttons on the Watershot. One presumes the BT will work at such short range, so you can get a readout on time/depth in addition to taking pictures with your camera, and with the right software you've got a dive computer to monitor N2. Innovative. But I use an Android phone....bummer.
