Sources in Apple's supply chain tell Cantor Fitzgerald analyst Brian White that the iPhone 6 could launch as soon as the second quarter of 2014.

The iPhone 5S is upon us so we're naturally wondering when the iPhone 6 will come out. Here's all you need to know about the rumoured iPhone 6 release date, specs and new features.
iPhone 6 release date 2014
History repeats itself people, so guess what? That's exactly where we are going to look for a first clue as the when we might see the iPhone 6.
Previous iPhone release dates:
iPhone 1st gen June, 2007
iPhone 3G July, 2008
iPhone 3GS June, 2009
iPhone 4 June, 2010
iPhone 4s October, 2011
iPhone 5 September, 2012
iPhone 5s/5c September, 2013
While the history books suggest that there will be an new iPhone 6 release date around September/October 2014, we have a gut feeling that Apple might – just might – shake things up a little bit and launch an iPhone 6 earlier than expected, just like it did with the iPad 4, which was launched just eight months after the iPad 3 (previous iPads were release 11-12 months apart). But for the record, the smart money goes on an iPhone 6 release date of September/October 2014.
