Wondering when the new iPhone 5 will land? Well, according to one supplier, the next generation smartphone is certain to be late, but is still likely to be hitting the shelves in September.TechRadar reports that analyst Gene Munster of Piper Jaffray claims he has 'concrete data points' for a launch delay, one of which is an iPhone manufacturing equipment supplier who told him that they received orders for the equipment later than normal. Specifically 'several months later'. That ties in nicely with other rumours, claiming the launch of the next iPhone is September. If you are winding down a contract, you might want to work with that month as an approximate guide.If those rumours are true, it's likely to be the headline act at what is usually a music / iPod event in September, as opposed to the June WWDC event, which is traditionally the iPhone unveiling. That same analyst also says the September dates fits in well with Apple's previous timescales. The new iOS 5 operating system tends to be launched ahead of the phone, two to three months as a rule. That again would see the hardware launching in September.The big feature for this model? Well, aside from an update in processing power and operating system, Munster claims a larger screen is the headline act, probably a four-inch screen. That also ties in well with past rumour. We'll know for sure in around four months if his first prediction comes to fruition.
