Samsung Galaxy S II update to bring larger icons, OTA updates widget
UPDATE: It seems that the Big Home update is an optional layer to aid people of older age who can't see the smaller icons well. It also includes larger calendar and other widgets to help with readability.
This might very well have to do also with Apple's patent infringement lawsuits, and show the judges Samsung is taking measures to reduce any similarities on the software side of things.
Samsung is also adding a System Update widget to the list, which will display the current software version, and notify you of any updates available for the OS, its overlay or the native apps.
