As soon as the veil came off of the table full of Samsung Infuse 4G devices at tonight’s AT&T Cinqo de Mayo event at Rosa Mexicano’s in New York City, we got to playing with the device. Below is our initial hands-on video where we take a look at AT&T’s newest and fastest Android device. The big deal here is the humungous 4.5 inch Super AMOLED Plus screen from Samsung. Plus, it’s AT&T’s first “4G” HSPA+ device capable of 21Mbps Category 14 download speeds. The Atrix 4G and Inspire 4G are only Category 10 HSPA+ devices that max out at 14.4Mbps.

The 4.5 inch screen really is pretty big as you can see here compared with the Galaxy S 4G.

Samsung and AT&T were very proud to announce the new Infuse 4G on Cinqo de Mayo at a great mexican restaurant in New York City.
