Apple will ship its iOS 6 upgrade at 1 p.m. ET today, according to reports and the company's past practice.
On Twitter, an Australian identified as James Edward Minaj posted purported release times for iOS around the world.
CNET first reported on Minaj's timetable earlier today.
According to Minaj and others, iOS 6 will hit Apple's servers at 10 a.m. PT, 1 p.m. ET.
That fits with Apple's previous practice.
Last year, Apple launched iOS 5 on Oct. 12 at 1 p.m. ET.
Although Apple has not officially announced the timing of today's iOS 6 release -- it did not do that in the past, either -- it did promise last week to deliver the mobile operating system today.
That, too, fits with past practice: Last year, it offered iOS 5 upgrades to current iPhone owners two days before the newest model was slated to start selling in its retail stores and pre-orders were to reach buyers.
Apple introduced iOS 6 in June at its annual developers conference, where Scott Forstall, Apple's top executive for iOS development, highlighted a handful of new features, including Apple's own mapping technology, an enhanced version of the Siri voice-activated digital assistant, and Passbook, a boarding pass and ticket manager.
iOS 6 can be installed on the iPhone 3GS, the iPhone 4 and the iPhone 4S; the iPad 2 and this year's third-generation iPad; and the fourth-generation iPod Touch.
The iPhone 5 and fifth-generation iPod Touch, which is also currently available for pre-order, will have iOS 6 pre-installed.
