Developer Steven Troughton-Smith has already found a lot of iPhone 8 information by digging around in iOS 11 code, and now he’s filled in a few more gaps, discovering the likely RAM amounts and camera specs of Apple’s upcoming phones.

Posting to Twitter, he claims that the iPhone 8 (which may eventually end up being called the iPhone X or iPhone Edition) will have 3GB of RAM, as will the iPhone 7S Plus (which may be called the iPhone 8 Plus).
