The long wait for Apple's next-generation iPhones may finally come to an end soon. The tech titan has started sending out invites for a special event on 10 September, hinting at the launch of its widely expected iPhones.

The official invitation which featured the Apple logo with an assortment of different colour circles carrying the line "This should brighten everyone's day," is said to be corresponding to the colourful panels of the budget-priced iPhone 5C. The event is due to take place on 10 September at Apple's Cupertino headquarters at 10:00 am PT.

Keeping to its tradition, Apple has kept its unreleased products under wraps, which seems to have helped the company garner tremendous attention. The company's upcoming devices have already generated enough hype in the market.

The latest news about Apple's event correlates well with the previous rumoured date for iPhone 5C and iPhone 5S. Besides this, Apple is also expected to announce the launch date and timings of its next iteration iOS.

Much has been talked about premium iPhone 5S and the cheaper iPhone 5C. Going by previous rumours, iPhone 5S will boast of a 4.0-inch screen with IGZO display technology and run on iOS v7.0 powered by the new Apple A7 quad-core processor with 1GB RAM. Apart from this, the device is expected to come with the same metal-clad frame but would feature a fingerprint scanner on its home button and a high-end camera on the rear side with dual-LED flash support. The iPhone 5S is rumoured to come in White, Gold Champagne and Black (Graphite grey) colour variants.

Regarding the affordable iPhone 5C, the device is expected to come with a 4.0-inch display with 1136x640p resolution and run on dual-core Apple A5 processor. Other stipulated features include 1GB RAM and multiple-colour plastic (tough polycarbonate based material) shells.

There are strong speculations that Apple will pull the wraps off the aforementioned devices, but it is not yet confirmed what the company will offer on 10 September.
