I have an iPhone 4 is there a fit bit tracker that will work with my iPhone

So far, it seems very unlikely that the iPhone 4 will ever work with it directly. The Bluetooth Protocol version which the fitbit device uses (4.0) is newer and more advanced than that of the iphone 4 (2.1, if I'm not mistaken). Without updated communications protocols (which I'm fairly certain are limited by the hardware of the iPhone 4), these two devices cannot communicate directly. I would imagine that you could use the app to input some information, though I do not own one and cannot comment specifically on that.
