The first images of what could be the 4.7-inch and 5.5-inch iPhone models were posted up on Twitter by tech insider Sonny Dickson.
The pictures show both devices side by side and viewers can see the front and back of them.
They seem to support many of the recent rumors regarding the handset as they include the much talked about rounded edges and larger form factors. More and more photos of the handsets keep popping up as the rumored September release gets closer.
Apple's normal release schedule usually leads to a fall launch for its flagship smartphone. It is unclear if the 4.7- and 5.5-inch models will launch at the same time as some insiders point to the larger version hitting stores in the beginning of 2015.
The iPhone 6 5.5-inch model is expected to be $300 on-contract, but that will not stop buyers from picking one up, according to analyst Raymond James Tavis McCourt.
He recently weighed in on the price increase for the iPhone during an interview with MarketWatch, and by basing his assumptions on the latest consumer data, he concluded that most of them would be willing to pay a bigger price for a larger handset.
"Our June consumer survey points to continued growth in the willingness of iPhone users to pay $100 more for a bigger screen iPhone, with now a full one-third survey respondents willing to pay $100 premium," McCourt said.
McCourt also pointed to the overall demand for a larger display.
"Data seems to suggest meaningful demand for a larger screen, which should logically mean the iPhone 6-cycle will be strong for upgrade sales, which combined with modest contribution from wearables should cause a modest acceleration in revenue growth in fiscal 2015," he continued.
