Google-owned Motorola Mobility is apparently quite serious about keeping recent smartphone buyers happy, enough to offer $100 towards the purchase of one of the company's latest devices to anyone who purchased a phone that's not in line to get Jelly Bean, Google's latest Android OS.

That pledge, made on stage earlier today by Motorola chief executive Dennis Woodside at the company's event in New York, only applies to a selected group of device owners. Specifically those who purchased one of Motorola's handsets since 2011, and who is not in line to get Android 4.1.
