Wow, did the summary ever get this wrong. The court said that the Samsung supplied Photo Gallery application infringes on an Apple patent related to a swipe gesture to move from picture to picture that bounces back to the current picture if the swipe is not completed.
The default Android Photo Gallery application does not do this, but Samsung customized the version included on its phones with TouchWiz (hence the Nexus S does not infringe and is not part of the ban or the Tab 10.1 that uses stock Android too) to replicate this functionality of iOS.
Also, the solution is not to provide Android 3.0 for the phones, Samsung will simply remove this extra functionality from the application (either by reverting back to the stock Android application or by simply removing it from their customized app) and provide an update for the affected models, thus negating the ban.
