Entries for slightly modified iPhone 4s and iPod touches are showing up in Apple's inventory system, an anonymous source says. The new iPhone models are reportedly identified with the codename N90A, linking them to the regular iPhone 4, the N90. The association may mean that the new SKUs are simply cheaper, 8GB iPhone 4s, rather than rumored iPhone 4S models, which would theoretically have the same amount of storage but a few upgrades, like faster processors.
