On the heels of the iPhone 4S going on sale, accessory makers immediately sprung into action. So this week, I present some of the fruits of these add-on efforts, such as a couple of unique 360 degree iPhone 4/4S cameras, as well as some handy iPod Nano and iPad attachments.
Track your riding speed, cadence, heartbeat and even location using this bicycle iPhone 4/4S clip case plus iBike Workout app ($150). The case communicates via an ANT+ standard wireless sensor that attached to your bike's rear wheel, and with any ANT+-compatible heart sensor. To listen to music and to answer phone calls while you're riding, use Bluetooth stereo headphones – you don't want a long headphone cord getting in the way. iBike Coach ($70) is a less expensive version sans the ANT+ heart sensor.
