Apple has slowly increased the storage capacities of its iPhones but it has yet to surpass offering more than 64GB of storage. That may change soon. A set of iPhone 6 schematics leaked on Chinese social network Weibo suggest that the Cupertino company will offer a 128GB variant of its next flagship phone. The leaked schematics apparently show how Apple is sourcing storage units for the iPhone 6. It looks like Toshiba is taking care of the 128GB modules on its own, while a small handful of companies are pitching in to provide 16GB and 64GB units. There’s no mention of a 32GB flash module, suggesting Apple may still only offer three options.
