Next-generation iPhones likely to focus on internal improvements.
4.7-Inch iPhone 6 Logic Board Shown With 16 GB Flash Storage
A set of schematics leaked in pieces over the past week and a half has included reference to various 16, 64, and 128 GB flash storage modules from several vendors for the iPhone 6, although it is unclear why there is no 32 GB option included on that list.
A new set of photos from Feld & Volk [Instagram page] and Sonny Dickson today that revealed the NFC chip present on the logic board of the 4.7-inch iPhone 6 also offers a good look at the flash storage module on this board. Based on the Toshiba part number, as seen on similar modules, the "7" indicates that this is a 16 GB module, suggesting the low-end iPhone 6 will continue to offer that amount of storage.
There are a few caveats, however, such as the possibility of this being a prototype or testing board using a 16 GB module not intended as a production option. Also, being a board for the 4.7-inch model, it is not yet known whether the rumored larger 5.5-inch iPhone 6 model will offer the same capacity options as the smaller model.
