Thanks to a leaked image from a Best Buy, it appears that we now know that the Motorola Droid RAZR and RAZR MAXX, alongside the HTC Rezound, will be receiving an Ice Cream Sandwich update. April 4th is the day for RAZR devices, and April 6th is when the Rezound gets in on the Android 4.0 action. The update will be available over the air, but we have no idea on the rollout schedule. By the looks of it, April is turning out to be a big month for smartphones and updates.
