Update coming for Motorola DROID RAZR HD and Motorola DROID RAZR MAXX HD; it's not Android 4.2.2.
The update, which weighs in at 50MB, will probably start rolling out OTA to the two handsets next week. The changelist shows that it will improve the reliability of the GPS feature, lessen the number of random reboots and categorize data usage to make for more accurate Data Metering. SMS messages that are read will be correctly displayed as read. Security for the phones will be improved after installing the update and both devices will offer the VMWare Horizon Mobile Switch application. This offers users a way to separate a phone into business and play modes and toggle between both of them when needed. It is an application tailor made for those who bring their own device to the office.
It is not an update to Android 4.2.2, but if it improves your DROID RAZR HD or DROID RAZR MAXX HD, it is a reason to welcome the update with open arms nonetheless.
