The Samsung Infuse, AT&T's ultra-light 4G phone, is .35 inches at it thinnest point (Ryan Hayslip)

At its slimmest point, the phone is 3.5 inches (8.99 mm), though it has a slight bulge at the bottom. It also sports a 4.5 inch screen, 1.2 Ghz processor and a rear-facing 8 MP camera.

The Infuse will also be the first AT&T phone to allow apps from outside the Android Market, AT&T’s Jeff Bradley told PCWorld.

That means Infuse users can use Amazon’s Android Market or other mobile app stores and load beta apps from developers.

The phone will cost $199.99 with a two-year contract. A $15 minimum data plan is required for the phone.

To sweeten the deal, AT&T and Samsung throwing in some extras: a $25 voucher for the Samsung Media Hub in for the first 500,000 to buy the 4G phone, an Infuse-only edition of Angry Birds, and preloaded trailers on the phone’s 2GB microSD card.
