Next Web reported many developers had noticed their user logs with the company referencing "iPhone6,1" hardware using iOS 7, which would be the next generation phone and operating system No. 7.
The company recently released its iPhone 5, which uses iOS 6.
The Chicago Tribune noted Wednesday no information is available in the logs on what new features might be included in the next generation iPhone.
The Tribune reported analysts expect the iPhone 6 will be released sometime in 2013.
The company is famously secretive about product development and equally guarded about launch dates.
