Apple seems to be ramping up the preparations for the release date of its new iPhone that is iPhone 6 and even the size is rumored as sales promos involving old iPhone models bring in.

In 2013 upgrades new features and technologies are added to the tech giants and it's a spirited effort for major launch and the dates are happening soon. In the past week, Apple made a partnership with U.S. Retail Giant Best Buy for a new deal that allows buyers to get $US150 price off on an iPhone 5 Purchase. Customers just have to trade there in their old iPhone 4 or iPhone 4S handsets to avail of the discounts.

The deal was offered a week after Best Buy swung the same iPhone 5 kit for only $US149, cutting down from the usual $US199 asking price that network providers slapped on new iOS smartphone releases.

Apple is seen to dispatch new chip architectures via its A-series processors, which according to experts will showcase new GPU capabilities that likely resemble or exceed the prowess seen before in AMP-powered mobile devices.

Another piece of the iPhone release date puzzle is Apple's AuthenTec purchase last year. In adding the Florida-based biometrics security firm, Apple watchers are convinced that future iOS device iterations will boasts off tougher security protocols.

The upgrade will be seen first via the iPhone 5S or the iPhone 6, both of which would come with fingerprint sensors underneath the Home button, protected too by sapphire coating.

Release date for the 5S is reportedly set for September 2013 while the 4.8-inch iPhone 6 is pegged for a June 2014 debut. However, it is expected that Apple could significantly advance the scheduled rollout if only to arrest the surging momentum of its chief rival.
