9to5Mac has posted photos of the iPad 2 screen. It is impossible to tell if it is in fact a retina display, but it is higher quality. It is lighter and 30-35% thinner than the current iPad's display.
On February 1, 2011, Apple seeded iOS 4.3 Beta to developers a third time. Earlier builds of 4.3 Beta have included personal hotspot functionality, better AirPlay video streaming, and an option to change the functionality of the iPad's side switch. It will also allow users to stop downloading apps and delete them while only partially downloaded.
