The iPhone 7 rumor mill is busy churning, with the latest leak perhaps finally confirming that Apple will be releasing a 256 GB model for the upcoming flagship smartphone.

The storage space for iPhones, specifically the lack thereof, has consistently been one of the major complaints of the device's users. While Android-powered competitors boast of expandable memory through microSD card slots, Apple's iPhones have traditionally offered limited storage spaces in 16 GB, 64 GB and 128 GB capacities.

Apple, however, may finally be addressing the problem, with rumors dating as far back as several months ago claiming that the iPhone 7 will come with a 256 GB option. The rumor has since been reiterated several times, with the most recent report on the matter released just last week. According to that report, the iPhone 7 will also be bumping up its minimum storage capacity to 32 GB.

An internal spreadsheet acquired by a Twitter leaker who goes by the name The Malignant could be the confirmation that most users have been waiting for on the 256 GB model of the iPhone 7. The spreadsheet, which is believed to belong to one of the manufacturing partners or component suppliers of Apple, shows three different storage capacities for the iPhone 7 and iPhone 7 Plus, specifically 32 GB, 128 GB and 256 GB.

With those capacities, Apple will be doubling the storage space in the three options currently being offered for the iPhone 6s and the iPhone 6s Plus.

The Malignant has a decent track record in his leaks, which should excite users who have been looking forward to bigger storage space for their iPhones. In addition, with the rumor being mentioned so many times, there has to be some truth behind the larger storage capacities for the upcoming iPhone 7.

However, it should be noted that the leaked spreadsheet has no obvious connection with Apple or the iPhone 7. The numbers indicated on the document follow Apple guidelines in terms of formatting, but that is not unique to the company.

While the 256 GB model of the iPhone 7 has long been requested, the move would likely lead to a higher starting price for Apple's flagship smartphone. It would be reasonable to assume that Apple will be keeping the price of the 32 GB and 128 GB models constant, while dropping the cheapest 16 GB price point and adding a new highest one with the 256 GB model.

The exact details of the iPhone 7 will not be fully confirmed until Apple makes an official announcement though, with the company expected to do so next month.
