Motorola Atrix 4G Update 4.5.141 Coming February 7th— It’s Not Android 4.0

We already reported last week that Motorola would be updating the Atrix 4G (potentially one last time) to include some new bugfixes. Now, we’ve received information regarding the contents of the over-the-air update that is scheduled for February 7th. The update will begin to push on next Tuesday, the 7th, and take a matter of days to weeks in order to cover all Atrix 4G owners on AT&T’s network. After updating, the software version number 4.5.141 will add the following new features and bugfixes:

• Latest Android security fixes from Android 2.3.6+
• Bluetooth voice commands while the device is asleep
• Improvements to the Messaging and Contacts applications (unspecified)
• WiFi settings update and AT&T Mobile Hotspot usage built-in
• Increases in stability, power management

The update will simply be on top of Android 2.3.X Gingerbread, not Android 4.0 Ice Cream Sandwich, as we expected. At this time, we cannot confirm whether or not the update will be the last over-the-air upgrade for Motorola Atrix 4G users. But, we still have no reason to expect an Ice Cream Sandwich upgrade for the device.

Other NVIDIA Tegra 2 devices, such as Motorola’s XOOM, have received Android 4.0 upgrades. But, there’s a clear difference between upgrading a “with Google” device that runs vanilla Android and a Motorola custom device with Blur. The Motorola devices that will receive Android 4.0 first include Motorola’s new Droid RAZR and Droid RAZR MAXX as well as the Motorola Droid Bionic. The XYBOARD and XOOM 2 will also receive an Ice Cream Sandwich update.
