As per reports, the new iPhone is speculated to be of 4.7-inch or even 5-inch in size. The reports also claim that the next flagship smartphome from Apple Inc will be thinner in size. Though, the company has not made any announcement regarding this device yet.

Earlier, market reports also said that the iPhone 6 will come in two sizes and both of these phones will be installed with fingerprint sensor. Fingerprint scanner was also used in iPhone 5S.

Apple's scanner is seen as a first step towards realizing the full potential for biometrics in personal electronics, heightening security for applications like banking and shopping while doing away with multiple passwords.

In December 2013, Apple CEO Tim Cook’s letter to employees started a debate about the launch of big screen iPhone in the tech arena. It was also anticipated that iPhone 6 will be out in the market much before its expected time.

"We have a lot to look forward to 2014, including some big plans that we think customers are going to love," Apple CEO Tim Cook said in a letter to its employees.
