I was looking for a USB OTG cable for my SGII on eBay and I saw someone selling a pair of adapters - one with USB female at the outboard end (i.e. standard OTG) and another one with HDMI female. Anyone know whether it's likely that the HDMI cable will work with the SGII? i.e. work like to yet-to-come MHL cable?

BTW the cables were US$8 for the set, post-free from China. They also had some standard OTGs with a right-angle plug at the phone end which looked pretty good.
