Although much of the attention is place on the big and beautiful 4.5-inch screen of the Samsung Infuse 4G, don’t forget the “4G” part of the name. Though AT&T has released other “4G” handsets — the Motorola Atrix and HTC Inspire — the Infuse is the first to be specced at HSDPA Category 14, making it the first of the lineup capable of 21Mbps data speeds. The Atrix and Inspire with HDSPA Category 10 are capped at 14.4Mbps. In case you were wondering, the Infuse carries HSUPA Category 6, capable of 5.76Mbps upload speeds.

The Infuse 4G is also responsible for another first: it is the first Android handset on AT&T to support app installs from third-party sources. Rather than locking down the Infuse and keeping users relegated to the Android Market, AT&T has once again enabled the ability to toggle apps from unknown sources in the settings menu. Fingers crossed this doesn’t somehow change before the May 15th launch date of the phone.
