The iOS 8 upgrade* of my iPhone and iPad went without a hitch. (I have to wait until I get home to do these things, because I cannot afford to make my phone inoperable while I’m traveling).
Android users point out that most of the ‘new’ features on the iPhone have been on Android phones for a long time. Oh well, that’s alright. It’s still all new to me. On the other hand some Apple fanatics say ‘It’s like getting a new phone’. Well, yes and no. A new phone would have a longer-lasting battery, for example. I wonder if the new iPhone 6’s are any better that way. Bigger screens eat up more battery power.
What I should still do is clean up (delete) all the silly Apps on my phone that I don’t use. I have way too many of those!
*iOS 8 is the operating system of the phone. It’s like upgrading one’s desktop computer from Windows 7 to Windows 8.
