Rooted Motorola Atrix 4G owners will be happy to know that they can grab AT&T’s HSUPA data speeds for themselves. Rather than waiting around for the carrier to enable the true high speed 4G that the phone is capable of, a couple of XDA members (dew.man and NFHimself) took things into their own hands. And fortunately for you all, they were only so kind as to share the goods with everyone else. As we said at the top of the post, you need to be rooted for this to work. Once you’re set with that, you can get the step-by-step directions at DroidMatters.
