Better late than never, right? Motorola's first dual-core handset, the ATRIX 4G, has finally received the green light for Gingerbread - and the OTA is a go. If you head into your Settings menu, and hit About Phone, then System Updates - the update should be waiting for you. If not, just wait a while - OTA's often take several days or even weeks to complete the "rollout" process.
What does the update bring? Well, Android 2.3.4 is the big star of the OTA. ATRIX 4G users will experience better app performance, UI refinements, and (hopefully) a slew of bugfixes. You'll also get a shiny new version of MOTOBLUR - hopefully one that's similar to what the DROID 3 is running, which we think is the best (well, least bad, maybe) version of the skin to date, and by a country mile.
Faster webtop browsing, improved Gallery and Music apps, and various other performance enhancements have also been included. You'll also be pleased to know the ATRIX's Tegra 2 chipset will finally do full 1080p playback - though we haven't see exactly how well it performs.
Otherwise, you get one final crowd-pleaser of a change: app sideloading. You can now gleefully check the "Unknown Sources" button in your Application menu under Settings, allowing you to install any old APK you want on your device. Huzzah, ATRIX users, the Amazon Appstore is now your oyster. You can check out Motorola's changelog here, which includes download and installation instructions.
