Apple may unveil its next iPhone on June 20 and could start selling the device in July, IntoMobile reports citing Japanese-language MacFan, which also claims that a low-cost iPhone model may hit retail channels in August and will target emerging markets like India and China.

MacFan isn’t the first and likely won’t be the last to predict an upcoming iPhone launch, IntoMobile says. Apple typically holds its WWDC developers conference in June and has used that event to unveil new hardware and software.

Apple analyst Gene Munster has suggested a summer launch for the next iPhone and this date is corroborated by Japanese Apple blog Macotakara, which claims that production of the iPhone 5S is in full swing.
