iOS 7 is a huge change so app designers will definitely need to update their designs to fit in with the new OS. Teehan+Lax, a company very well known for its very well put together iOS templates has kindly updated its PSD kits to add iOS 7. The kit is based on BETA 1 of iOS 7 so things may change when it comes to final release but they have promised to update the PSD if things do.
This PSD is based on the beta, so be aware that design decisions you’ll be making when using this file will need to change as the OS becomes more refined. We’ll keep it up-to-date as best we can. Whatever your use, we hope you enjoy it.
