Official Motorola Droid 4 specs leak out: it’s a Razr with a keyboard.

A document showing the official specs and features for the Motorola Droid 4 has leaked out, shortly following the report about its upcoming December 8 launch. The leaked document confirms a number of previously-rumored details, including the fact that it looks like a slightly smaller-screened Droid Razr with a slide-out keyboard.

So here’s what’s what: the Droid 4 will feature a four-inch screen, 4G LTE, front webcam and 8MP rear camera. It’s going to run on a 1.2GHz dual-core processor and 1GB of RAM, and will feature “Droid Razr styling,” which basically means that it will, in fact, look like the Razr if you added a five-row slide-out keyboard behind the screen.

The rest of the spec is rounded out by 16GB of built-in storage, a microSDHC slot for adding more, and software features that include MotoCast streaming and MotoPrint wireless printing. Other notable features include details that looks pulled from the iPhone – like a special tool that’s needed to open the back cover (for reaching the microSDHC slot and SIM card) and a non-replaceable battery.

According to Droid-Life’s sources, Verizon staff is already undergoing training for the incoming phone, which could mean that we’re close to a launch. If it’s indeed set for a launch on December 8, then this phone is headed for a collision course with Samsung’s Galaxy Nexus, or the first phone to run on Android 4.0. That last part could be huge, since the Droid 4 will initially launch running on an aging Android 2.3 OS.
