Since Apple has put the iPad SDK in the hands of developers, it is also interesting that designers start to have contact with the creation of user interfaces for the new product, and there is no better place for that than good Photoshop although the creating Apple interfaces are also good.

The website claims that the controls available in the document were created using vectors, so they are fully scalable within Photoshop. By default, you will already be able to use some of the new controls introduced by Apple and work on the new workspace with higher resolution (768 × 1024), but the PSD creators make it clear that this is the first version of it for the iPad, which means that new elements will emerge over time.
