The iPhone 6 may be released in September 6, according to latest rumors. Apple fans are already counting down to the company's next generation smartphone, and rumors are again swirling regarding the likely iPhone 6 release date.

According to those rumors, the iOS 6 release measured against the iPhone's release in 2011, indicates that late September could be the best bet for the next Apple smartphone. The iPhone 5 was unveiled on September 12 last year, and was available on the U.S. market 10 days later.

According to Cult of Mac, it expects "two new device types, and this doesn't mean two different color or memory variations." Does this mean two different screen sizes??

Latest reports suggested that Apple is testing different screen sizes for both the iPad and the iPhone. An iPad screen measuring just under 13 inches is said to be in its testing phases. The Wall Street Journal reported that Apple asked its suppliers "for screen designs for a new tablet measuring slightly less than 13 inches."

Meanwhile, some analysts have pointed to a new Walmart iPhone 5 fire sale as an indication of the upcoming release date for the next generation iPhone device. Walmart is currently selling the iPhone 5 for just $129 and the iPhone 4S for just $39. That has sparked some rumors that the store is trying to clear its stock of the older devices to make way for the iPhone 6 to be released as early as August 2013.

The iOS 7 is expected by many to have a scheduled release date for September 18, but if the iPhone 6 is unveiled on September 6, the iOS 7 releae may come earlier. Some believe Apple release some new hardware after the iOS is unveiled. Rumors are that the iPhone 5S could be released in the days after the iOS 7, with the iPhone 6 coming a week later. The iPhone 5S will be cheaper and look to attract a different crowd than the top of the range iPhone 6, according to those rumors.
