Teehan+Lax has released iPhone 4 GUI PSD (Retina Display). For anyone designing for the retina display (640×960) it really is quite a different experience. When you work at 100% everything seems absolutely huge but small details get lost when viewing it on the device. You really need to be mindful of how it looks on the phone since your monitor displays things so differently.

The file is huge, both in file size (62.7MB) and dimension (4074×2986). You’ll need to work at 25% – 50% even on the largest screens to roughly grab elements before zooming into 100% for the actual work.
