According to unnamed sources, 9to5mac are reporting that the iPhone 4S – “N94” – will be released with three different storage capacities – 16GB, 32GB and 64GB.
Currently, the iPhone 4 is only available in 2 sizes: 16GB and 32GB. The source of the rumor comes from images of an iPhone 4 with storage of 59.1 GB, which shows that Apple have been experimenting with a higher-storage device.
What sizes Apple will actually release is up for argument. It seems unlikely that an 8GB model will appear, but all will be revealed at Apple’s iPhone 5 / iPhone 4S media event on Tuesday October 4th.
