Apple iPad GUI PSD Version 2 has been completely redesigned from the ground up. it includes all the elements you need to design proof-of-concepts or production ready assets. The last version of this file was riddled with issues like blurry edged buttons and incorrect “bevels”. These issues have been addressed as best they can using Photoshop’s shape layers and layer styles. If you’re modifying any of the vector elements be sure the shapes are sitting on full pixels or your assets will begin to look blurry.
