Go to Settings, General, Software update to download iOS 8.1.2, which is compatible with iPhone models 4S and newer. We've seen difference sizes for the update, ranging between 16 and about 23MB, on different devices for over-the-air transmission.

While Apple had problems with its initial iOS 8 fixes, the last couple have gone smoothly. Version 8.1.1 was released in mid-November and brought performance improvements with it.

As of Nov. 24, 60% of mobile Apple devices were running iOS 8, according to the company's developer support page.
