By now, we pretty much know the game: Apple releases a new model number of iPhone, then the next year it releases the "s" version. 4, 4s, 5, 5s - you get the picture.
This year is looking like it could be a bit different. We're learning that Apple still plans an incremental upgrade - the 6s - and it could be the biggest, most dramatic incremental upgrade ever.
Apple usually keeps pretty tight-lipped on its products before their big reveals, but rumor from a well-placed source among Apple analysts is leaking a pretty interesting scoop. First, the new iPhone 6s will still have two different size options, but that's where the similarities seem to end.
Nearly everything inside will be new. The source says the new versions will jump from 1 GB of RAM up to 2 GB. That could allow you to have more apps open at once or allow software developers to make even more complex apps.
