Mashable is suggesting that the iPhone 5 is due in June:
According to a Foxconn recruiter, weâ€™ll see a new iPhone in June of this year.
In the interview, a reporter asked the recruiter how many people the company was looking to hire, and he answered â€śWeâ€™re looking for 18,000 employees â€¦ for the fifth-generation phone.â€ť
The reporter went on to clarify that the recruiter was talking about the iPhone 5, and the recruiter added that the next generation of the handset will come out in June.
After the the initial iPhone release, the company launched an iPhone 3G, iPhone 3GS, iPhone 4, and iPhone 4S.
The June rumor, of course, should be taken with a grain of salt. Rumors of the iPhone 5 started almost immediately after the announcement of the iPhone 4S last year.
