Samsung Infuse 4G

Samsung Infuse 4G

Don't believe the hype: the Samsung Infuse 4G may be AT&T's first true 4G cell phone, but AT&T doesn't appear to have the network to back up the Infuse's HSPA+ 21 speeds. The Infuse is the first phone we've tested that packs an extra-large, 4.5-inch touch screen. It's also amazingly thin—thinner even than the Samsung Galaxy S 4G ($199, 4 stars) on T-Mobile. Still, a few quibbles here and there add up to a phone that's very good, but not great. It still makes the cut for our list of The Best Phones on AT&T.
