Apple will introduce new versions of iOS and OS X at its annual developer's conference.
Apple CEO Tim Cook: iPhone 6 and 6 Plus Demand 'Far Outstripping' Supply
Supplies for the iPhone 6 and iPhone 6 Plus have remained tight since the launch of both devices last month, as new iPhone 6 orders still show a shipping estimate of 7-10 business days while the iPhone 6 Plus is still showing a shipping delay of 3-4 weeks. It is worth noting that the iPhone 6 has been mostly available at Apple's own stores and other retail locations, while the iPhone 6 Plus has a constrained supply in-store.
According to a report by The Wall Street Journal, Apple delayed plans to mass produce the larger 12.9-inch iPad in order to shift its resources towards the iPhone 6 Plus as it has remained unsatisfied with the production output from its suppliers for its larger iPhone. A report from earlier this month also stated that the company is shifting its production balance towards the iPhone 6 Plus which may gradually improve its supplies of the larger phone.
