The latest update to iOS dropped last week, with Apple releasing iOS 11.1.1 to the general public. While the update is minor, for some iPhone owners the install takes on greater importance. The main problem, which is fixed by iOS 11.1.1 revolves around the keyboard and auto-correct. On some devices, iOS users can't type the letter "i" at all. The keyboard automatically replaces "i" with a strange character, sometimes appearing as an "A" followed by a question mark symbol.
