We've known AT&T intends to enable HSUPA support for its mighty Atrix soon, but if you want it now (and we mean now), two restless XDA contributors are delivering some instant gratification for your upload woes. Today, dew.man and NFHimself released a modified radio file that allows Atrix owners to send data properly -- a feat iPhone users simply take for granted. This mod requires that your device be rooted, but reactions in the forum are ranging from ecstatic to elated (and everywhere in between). Of course, you could wait for AT&T's official release, but where's the fun in that? Hey, it's your phone, so take ownership already! Everything you need to know is in the source link below.
