To keep hands off your iPhone device, you need to download iSecurity. An alarm system with 3 different modes; Charger, Headset and pickup mode AKA "motion".

"Charger"
Connect your charger or headset and activating the alarm. iSecurity alerts you with an intense alarm when ever your device is unplugged against your will, (good, when in public place, charging your device i.e. airport, coffee shop, school or library)

Pick up mode; works simular to charger and headset mode (but without using either) its "motion" sensitive.
You select "pickup mode" and activate the alarm, you'll have 5 seconds to place your device down. Afterwords, If anyone picks up your mobile device, the alarm will sound, alerting you that someone has activated the alarm (this mode also works great if you have it in your briefcase, purse, backpack or any other personal item) just activate the alarm, leave it in/with your personal items, if someone moves it, the alarm will be activated! Protecting your device and your personals!
