Yesterday, Apple seeded iTunes 10.5 beta 9 to developers with iTunes Match beta. There are 2 iPhone models references found in this iTunes beta, the iPhone 4S black and the white.
iTunes beta only holds two iPhone 4S references: iPhone 4S black and iPhone 4S white versus the four iPhone 4 references of black/GSM, black/CDMA, white/GSM, and white/CDMA. This may also reaffirm the dual-mode iPhone 4S, both CDMA & GSM technologies will be supported in one handset.
The new iPhone is expected to feature the dual-core A5 processor from the iPad 2, 8 megapixel camera, 1GB of RAM, Nuance-based speech-to-text Dictation, and the Assistant feature.
