According to iMore's sources, some of the rumors we've heard about iPhone 5 hardware, like a reduced-sized docking connector, are a done deal. There are others -- covering some areas we're quite interested in -- Apple has supposedly yet to commit to. These include certain decisions about the phone's body, especially regarding what materials will make up the handset's shell and the size and aspect ratio of its display.
Whatever Apple ends up going with, the source behind this info claims it won't be a huge change -- no five-inch screens. One more aspect of the phone's design that has reportedly been finalized is the continued presence of a physical home button, which makes sense given the new components we've seen.
Even with Apple still working through these final decisions, the next iPhone is still expected to launch in or around October.
