Each Motorola ATRIX owner has seen their fair share of ups and downs, the biggest down of all perhaps being the lack of up(load speeds), as the ATRIX 4G doesn't have HSUPA support out of the box. AT&T has promised a fix for this and we've even seen phantom updates arise to fix the issue. As always, though, when carriers and manufacturers fail us, who do we look to? XDA, of course! This occasion is no different, and user dew.man has come through.
