According to AllThingsD, Apple might launch its next generation of iPhone on September 10.
There is no detailed information about this new iPhone yet, it's also unknown whether it's a cheap one or other kind of versions. But it will equip with iOS 7 and Apple may launch the next generation of Mac OS--Maverick in next few weeks.
Since Apple acquired finger print recognition manufacturer AuthenTec with $356 million and it also applied the finger print unlock patent, so the next generation iPhone may come with finger print recognition function.
