AT&T has leaked in a Facebook response that the Motorola Atrix 4G an HTC Inspire 4G will be getting HSUPA 4G support with it's April software update. In addition, the Samsung Infuse 4G will come HSUPA enabled right out of the box. AT&T has caught fire of late for hobbling HSUPA 4G on their hallmark phones while they proceeded to 'test the network.' That caused many of those Atrix fans who bought the hype brought on by the Atrix winning best cellphone at CES and dove in with both feet, only to find a 4G phone only running at 3G speed. That will all change come April.
