Yesterday, BoxWave unveiled a keyboard case for the Apple iPhone 4, and today the device made an appearance on the FCC, above.  The device is manufactured by a Chinese company called Shenzhen Ctech Science and Technology Development Co., Ltd., and is known by the model number S1.

It appears that the S1 case will bear the BoxWave brand in the United States, although we wouldn’t be surprised to see non-branded imports of this case showing up as well.
