Another fun stuff that you can do with your iPhone
<blockquote>No jailbreaking. No WiFi. Stock receivers. I fly model airplanes and helicopters with my iPhone. I use an off-the-shelf 2.4GHz module and a custom iPhone app. The app is now in beta testing. I use the phone's headphone jack to communicate with the Spektrum module. I make no modifications to the module or the receivers. This application does not use WiFi, Internet, external servers or microcontrollers.</blockquote>
