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.

The Motorola Atrix 4G has a 1Ghz dual-core processor running Android 2.2 (Froyo). But it’s more interesting feature is the optional 11.6 inch screen, and full QWERTY keyboard that users can buy to turn the Atrix into a full blown desktop replacement, though it oddly runs Ubuntu as an OS in this configuration. Not really the prime go to OS for the business world, but still a popular flavor of Linux nonetheless. And it won’t only be exclusive to AT&T either as it look like Sprint will also get the Atrix later this year. Check out our review here.

The HTC Inspire 4G has a mammoth 4.3-inch S-LCD touchscreen display which offers a rather crystal clear presentation. It’s powered by a a Snapdragon MSM 8255 1000 MHz processor, has a hefty 8-megapixel rear facing camera and comes with a rather cool GPS tagging feature which we really like. HTC says it’s 1230 mAh pack provide up to 6 hours of talk time or 372 hours of standby. Check out our review here.

Lastly, the Samsung Infuse is based on the Samsung Galaxy S with a huge 4.5″ Super AMOLED plus multi touch screen, 1.2 Ghz Hummingbird processor, and dual cameras including an 8MP rear facing camera and 1.3MP front facing camera for video chat. The Infuse is dubbed the thinnest device AT&T has ever carried and will run Android 2.2 (Froyo) out of the box. It recently cleared the FCC and it should be ready to release next month according to the Facebook post. We’re certainly looking forward to checking it out, but meantime, since it’s based on the Galaxy S 4G, you can look out our review here.
