Any recommendations on a HRM attachment for the iPhone 3G and a waterproof mountable case?
I use EveryTrail and really like the mapping and being bale ot see where I am, I'd also like to be able to add HRM to see how my fitness is improving, and its a pain to keep stopping and unlocking and checking the map.
Do the HRM's attach thorugh the audio jack?
Any help/suggestions would be appreciated
