iPhone is once again in the rumour mill, with speculation mostly centred around the upcoming model's screen size.
The latest report on iPhone 6 comes courtesy Chinese microblogging platform Weibo, where a user called C Technology has posted that the model will come in two screen sizes - 4.7-inch and 5.7-inch. Citing Foxconn executives, the post says that the two models will feature eye scanning biometric technology, along with the Touch ID fingerprint scanner.
The report also says that the screen size of the upcoming iPhone phablet may vary. The Wall Street Journal has earlier reported that Apple is experimenting with an iPhone with 6-inch display.
An earlier report by Chinese technology website Digitimes also says that the next iPhone will have a 4.7-inch screen and may be unveiled as soon as May 2014. This model will be developed using the 20nm processer by Taiwan Semiconductor Manufacturing Company.
It is expected that the upcoming iPhone 6 will have a 64-bit A8 processor, scratch-resistant sapphire glass body, wireless charging and built-in solar panel.
Wells Fargo analysts have downgraded the Apple stock from 'Outperform' to 'Market Perform' over concerns about the price of iPhone 6. The investment bank is concerned that the profit margins of iPhone 6 would be lesser than that of current and previous models since the component cost would be higher. After the downgrade, Apple shares fell 1.4%.
Apple is also expected to unveil the iPad Pro tablet with a 12.9-inch high-resolution screen this year, which will be aimed at students and business users and replace the Macbook Air. Other rumoured products in the company's 2014 lineup include a smartwatch and a HDTV.
