iPhone 6 release date may happen very soon as previous iPhones are for sale in Amazon.

Consumers will see a new iPhone very soon as the online retail giant dropped down the prices of former iPhones to probably exhaust old stocks.

iPhone 5S is normally priced at $1,199. But Amazon listed the device for only $709.99. iPhone 5, which is no longer available in Apple Online Store, costs $565.10 that slashed 25% off the price of the device.

The 16 GB version of iPhone 4S is available at $384.50, while the quite old iPhone 4 can be bought at a price of $209.99.

Reports claimed iPhone 6 will come in two variants. BGR cited KDB Daewoo Securities analyst saying two iPhones will arrive this year. One will come with a 4.7 or 4.8-inch display, while the second will have a 5.5-inch screen.

Rumors indicated iPhone 6 will also come in two variants like the previous iPhone 5S and iPhone 5C. iPhone 6 is expected to arrive in two models, one is speculated to be the company's phablet, which will basically start a new line. The other handset will be the real successor of iPhone 5S.

iPhone 6's rumored features include A8 processor, iOS 8 and fingerprint sensor. It is speculated to be released in June at the Worldwide Developers Conference. Also, the handset will most likely pack the new version of Apple's operating system.

Patents from Apple hinted on some of the possible specifications of the next iPhone. Patents described curved or flexible screen with liquidmetal and Sapphire glass covering for the screen display, an improved Siri and gestures control. iPhone 6 release date is expected either in June or in September.

iPhone 6 release date is expected to happen in late summer with some reports saying the device will be released in June at the Worldwide Developers Conference. Other reports claimed the smartphone will be launched in September.
