Galaxy S III changes pin layout, incompatible with previous MHL adapters
 

If you've pre-ordered a Galaxy S III and can't wait to see its display mirrored to the silver screen, add one more thing to that pre-launch shopping list: a new MHL dongle. According to UK retailer Clove, a change in the phone's connector pins renders it incompatible with previous Samsung-made adapters. Sammy's new microUSB-powered connector supports 1080p output via HDMI -- though it reportedly doesn't play nicely with 720p displays -- and rings up at $40 on Amazon. Mosey past the break for a video unboxing of the dongle.
