I updated my iPhone and iPad. Took a few tries due to everyone else trying to upgrade today but once it started it did not take long at all. 20 minutes or so. However I do not like the new graphics. They went from 3D to flat graphics. Maybe I will get used to it but my wife does not want to upgrade her iPhone and iPad. She only uses the phone and email and what she has now works just fine and is prettier looking.
