Motorola sends up Atrix 4G HSUPA update
The HSUPA update promised by AT&T for Motorola's Atrix 4G handset is now being sent out over-the-air. Update 4.1.83 brings with it HSUPA support for the handset and Android 2.2.2. Users who have downloaded it already are reporting three times faster uploads than before, when they usually dipped well below 1Mbps. Downloads have also increased slightly with the speed hike.
As Motorola isn't yet freely releasing the software, users need to manually check for it from their handset's menu. Once the update is downloaded, they need to install it, and the phone will automatically restart.
AT&T had intentionally disabled HSUPA upload speeds on the Atrix 4G, Inspire 4G, and most other phones under the claim that it needed to certify performance on the network. [via DroidMatters]
