iPhone 6s sales
Apple will roll out the new iPhone models in more than 130 countries before the end of 2016Reuters

Apple is doing better on the supplies front with its new iPhone iterations - iPhone 6s and 6s Plus - than the previous models. The iPhone duos first went on sale on 25 September in a number of countries across the globe such as Australia, Canada, China, France, Germany, Hong Kong, Japan, New Zealand, Puerto Rico, Singapore, UK and US.

Apple set a new sales record with 13 million units sold within a mere three days of the global rollout. Despite such a huge demand, Apple appears to have made stocks available with no supply constraint, according to analysts. A recent poll, conducted by renowned analyst Gene Munster of Piper Jaffray across 54 Apple stores in New York, Florida and Texas, revealed that all stores had 50% stocks available for the 64GB iPhone 6s and 6s Plus units for AT&T and Verizon. This was disclosed in Munster's note issued to investors, a copy of which was obtained by Apple Insider.

This figure is against 6% SKUs (Stock Keeping Units) for the iPhone 6 and 12.8% for the iPhone 5s when they were released in 2013. He added that shipping of iPhone 6s takes three to five business days (according to the product page) whereas it is two to three weeks for the 6s Plus. Comparatively, this is an improvement over 2014's delivery time, given that it took 7-10 days for the iPhone6 and three to four weeks for the 6 Plus to be shipped. Munster believes that Apple's manufacturing process has been sorted out with the release of the iPhone 'S' model, which in turn has allowed the company to meet supply demands.

After its initial launch, Apple rolled out the latest iPhones to more than 40 countries, including Andorra, Austria, Belgium, Bosnia, Bulgaria, Croatia, Czech Republic, Denmark, Estonia, Finland, Greece, Greenland, Hungary, Iceland, Ireland, Isle of Man, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Maldives, Mexico, Monaco, Netherlands, Norway, Poland, Portugal, Romania, Russia, Slovakia, Slovenia, Spain, Sweden, Switzerland and Taiwan, starting 9 October. The handsets will be available in India, Malaysia and Turkey on 16 October and in more than 130 countries by the end of 2016.
