iPhone 5S Release Date Rumors Specs, Features: Apple Sends Out Invites for September 10 Event / Budget iPhone 5C Also Unveiled?

Apple has finally sent out the invites to its upcoming keynote event, scheduled for September 10. Does that mean the new iPhone 5S has a release date set for the same day?

The event will take place at Town Hall in Apple HQ, Cupertina at 10 AM Pacific time. Apple is expected to unveil the new iPhone 5S along with full specs and features for the company's flagship device. Along with the new iPhone 5S [or iPhone 6, no one knows yet], Apple is expected to release an all-new budget iPhone model [the iPhone 5C?] as well.

Though there's no concrete evidence supporting an iPhone 5C release [other than a few alleged photo leaks showing off a phone that resembled the iPhone 4 with plastic casing], Apple experts say a low-cost alternative to the popular smartphone could increase market share in regions like China dramatically.

Apple CEO Tim Cook has been hinting all year for great things in 2013. Could it be the jump to the iPhone 6, a new iPhone 5C, or a new iPad Mini? Though they're just rumors, September 10 is sure to be a big day in the tech industry.
