Been at it with the new iOS most of the week on both my iPhone 6 and my wife's 5. So far so good. The usual minor adjustments that come with new OS tweaks but no big problems. Fortunately I'd read on this forum about the new home button protocols. Messaging seems to have some neat new functions that we haven't used and completely figured out, but that will come in time. I can't say that I'm unhappy with the update.
