Last month, AT&T responded to complaints that Android phones running on its network were crippled to disable HSUPA for high-speed uploads. The company quickly went on the defensive, first trying to argue that it wasn’t actually “capping” speeds by selling smartphones with this mode disabled. Perhaps it realized that no one was buying its claims of innocence, as it followed-up a couple weeks later with a promise to bring HSUPA to the Atrix 4G sometime in April. Though it’s yet to announce that a patch is ready, it may already be going out to users, as at least one Atrix owner has reported receiving a series of updates finally enabling HSUPA for his phone.
The Atrix 4G owner who noticed these updates first received one bringing his phone to 4.1.75.MB860.ATT.en.US, at the same delivering an incremental Android update from 2.2.1 to 2.2.2. It looks like this lays the groundwork for the second update, 4.1.83.MB860.ATT.en.US, to make the changes necessary to enable HSUPA support. Post update, the Atrix 4G was showing upload speeds north of 1.5MBps.
We’re hoping this is just the start of a larger push by AT&T to get the patch out to all its Atrix 4G owners, but we’ve yet to receive confirmation. If your Atrix has taken the updates and is now performing up to its potential, let us know in the comments.
