iPhone AirPlane Mode When Docked

Hi, is there anyway to make the iPhone 4S ios5 Automatically go to Airport mode when connected to a power source/ iPod dock. and then automatically turn of airplane mode when disconnected from the power source

The dock i have keeps interfering at night, and it would be useful once i dock it, it switches on airplane mode for me. Or at least turn off airport mode when i disconnect it.

My old 3G use to prompt me to turn on airplane mode, and then go back to normal mode once disconnected?

Any help would be appreciated

Any Cydia Apps available to do this. ( Still trying to work out how you jailbreak a 4S)
