During its press event in New York City earlier today, Motorola promised to upgrade “most” of its 2011 device portfolio to Android 4.1. But Motorola CEO Dennis Woodside also said that the company will offer a $100 credit to any users whose devices don’t get upgraded that they can use to buy a new DROID RAZR HD, DROID RAZR MAXX HD or DROID RAZR M smartphone. Woodside said that some of Motorola’s older devices actually ran slower on Jelly Bean, and that it didn’t want to degrade user experience for the sake of installing Jelly Bean. Motorola on Wednesday also announced the availability of developer devices for those who wish to root and modify their Android smartphone. The DROID RAZR M Developer Edition can be preordered now for $549.99.
