How much longer should Apple device users wait for the release of the iOS 9 update?

Since Apple Inc. CEO Tim Cook announced during a keynote event on Sept. 8 that the tech firm will roll out its latest mobile operating system update on Wednesday, Sept. 16, iPhone, iPad and iPod touch owners have been looking forward to downloading iOS 9. 

Although Cook announced the actual release date, he did not mention the exact rollout time. But several sources offered an estimate for the arrival of the iOS 9 update based on the pattern of past iOS releases from the Cupertino-based tech giant. 

According to GottaBeMobile, Apple Inc. normally drops iOS updates between 9 and 10 a.m. PST. This could also be applied to the upcoming iOS 9 release. This means that those in the Eastern and Central time zones should expect to get the updates from 12 noon to 1 p.m., while those in the Mountain time zone might be able to start downloading the newest iOS update from 11 a.m. up to 12 noon. 

Meanwhile, those who live outside the U.S. can expect to get iOS 9 in varying time frames. Some could be earlier or later than the U.S. schedule. The estimated iOS 9 release times in major cities worldwide are as follows: 

• London – 5 to 6 p.m.
• Moscow – 8 to 9 p.m.
• New Delhi – 9:30 to 10:30 p.m.
• Shanghai – 12 midnight to 1 a.m.
• Tokyo – 1 to 2 a.m.
• Melbourne – 2 to 3 a.m.
• Auckland – 4 to 5 a.m. 

These are just estimated times for the global iOS 9 release, which means that the operating system could be rolled out earlier or later than the expected time frames. 

The list of Apple Inc. products that are compatible with the new iOS 9 includes the iPhone 6, iPhone 6 Plus, iPhone 5s, iPhone 5, iPhone 5c, iPhone 4s, iPad Air 2, iPad Air, iPad 4, iPad 3, iPad 2, iPad mini 3, iPad mini 2, iPad mini, as well as the iPod touch fifth-gen.
