Samsung released two new firmware updates for the SW-252B today.
R702 was posted on their korean website. It's supposedly for the domestic market, but it does work on the SW-252B's sold here in the US. I can't read Korean, but you can get more info and download it
R701 is available on their English website. According to their webpage, the changelog is:
Improvement: It supports Maunt Rainier format.

I'm sorta confused on why they released two different firmware versions. If you know why, please share with everyone.
