The Google (Nexus One) Phone has reached the FCC as model number PB99100 built by HTC, according to an Engadget report.
The phone operates on HSPA 900 / 1700 / 2100 plus quadband EDGE and is capable of both 2Mbps up and 7.2Mbps down. Additional features include microSD expansion, 802.11b/g WiFi, and Bluetooth 2.1 + EDR.
Unfortunately, it seems as though the device will not work on AT&T's 3G network, "Only WCDMA Band IV was tested in the Part 22H / 24E / 27 Report, leading us to believe that the Nexus One is going to be HSPA 900 / 1700 / 2100 (a pretty common tri-band 3G setup) plus quadband EDGE. Sorry, AT&T, but that's how the cookie crumbles."
