In case you weren’t aware, the 4G phones (Inspire 4G and Atrix 4G) have had their upload speeds on AT&T throttled due to the fact that HSUPA (the feature that allows phones to upload at 4G speeds) isn’t enabled on those devices. AT&T has previously mentioned that HSUPA was still under testing and that they wanted to perfect the experience before letting those phones have it.
The update for the Inspire 4G has apparently started rolling out, bring HSUPA and a whole bunch of other bug fixes and performance improvements to the HTC Android phone. As for the Motorola Atrix 4G, AT&T has finished testing and will begin rolling out the update in the coming weeks as well. Keep an eye on your phone for the update notification if you’re using the Inspire 4G or Atrix 4G. If you’ve received the AT&T update, let us know if your upload speeds improve noticeably.
