If you’re planning on buying or receiving a new iPhone 6s tomorrow, you will be asked to upgrade the operating system on the device immediately.
Apple has released a special version of iOS 9.0.1 that’s specifically aimed at the new iPhone 6s and 6s Plus. The OS version was pushed out to the public yesterday, but, oddly, that version didn’t include support for the new phones.
The iPhone 6s and the iPhone 6s Plus will ship with iOS 9.0.
The update is nothing major. It fixes a couple of bugs, including a “Slide to Upgrade” dialog problem that was preventing some users from upgrading to iOS 9. The update also fixes an issue that caused some paused video images in Safari and Photo to appear distorted, and another that cause some alarms and alerts not to sound.
