Market analysts have predicted that Apple's 2014 marquee handset, dubbed as iPhone 6, will feature a significant upgrade from its predecessor. Now, scoop from an trusted Australian tipster has surfaced online corroborating previous reports.

Popular Apple devices spy, Sonny Dickson has revealed in his series of Tweets that the Apple iPhone 6 will boast of Ultra-Retina display with a pixel density of 389 ppi (pixels per inch) and run on A8 processor having a staggering CPU speed of 2.6GHz, faster than the recently unveiled Samsung Galaxy S5's Qualcomm Snapdragon 801chipset, which clocks 2.5GHz speed.

He also claims that the upcoming iPhone will feature a slim body measuring just 5.59 mm in thickness. That's just .09 mm more than the Gionee Elife S5.5, which is touted as the world's thinnest smartphone.

Though the revelations have no proof of authenticity, the track record of the Australian blogger is pretty impressive, especially regarding Apple devices.  Last year, he accurately foretold about Apple's plastic handset iPhone 5C, so one can to expect his predictions to come true.

Apart from the iPhone 6, Apple is also slated to launch the company's first phablet (many tech blogs are dubbing it as iPhablet), a 5.5-inch big-screen handset with IGZO (Indium Gallium Zinc Oxide) display with resolutions 2272x1280p. It is also said to house Apple A8 CPU, 2GB RAM and come in 16GB, 32GB, 64GB and 128GB storage variants, said South Korean market watch-dog KDB Daewoo Securities.
