Sony Ericsson’s Xperia Arc has touched down at the FCC, providing us with a treasure-chest of pictures, technical documents, and user manuals for the upcoming Android smartphone.

While there are plenty of 1GHz Android phones to compete with, the Xperia Arc has a leg up on the competition thanks to its extreme thinness and impressive auto-focus camera. We got a chance to interact with the phone at the CES earlier this year and mostly liked what we saw.

According to the FCC filings, the Xperia Arc supports HSDPA and HSUPA for high-speed 3G, and will operate on UTMS bands 2 and 5, pegging the phone for AT&T’s network.

While we’re certainly at no loss for early looks at the Arc, you can now get a glimpse at the phone’s inner workings, as well as check out the 8.7-millimeter-deep design up against a ruler for comparison.

We’re expecting to hear about a release date for the Arc somewhere around the beginning of April. There’s no word yet on what it will cost in the States, but it’s going for around $750 off-contract in the UK.
