It's been a while, so here's some more speculation around a summer launch.
9to5Mac says it's spoken to a Foxconn employee who says a new iPhone is ready for production.
There are multiple design options floating about apparently, but none has been finalised. However, the story does specify that the device will have a four inch plus display and a symmetrical form factor (as opposed to teardrop-shaped).
It also asserts that the design will be different from iPhone 4/4S.
This source is the same that indicated to 9to5Mac (correctly) that the iPhone 5 was not happening last year as was widely speculated.
Does that make this accurate? God knows.
