I just did this update on my iPhone 5s. WOW. I can't believe how much stuff this has changed. Great stuff, this. I read is while it was uploading. It says its the biggest update ever, or something. New favorites list and recent calls shows with a double tap. The map app is suppose to have fly-over tours of cities. Texting can be done with short audio texts. The keyboard has emoticons(crazy unusable amounts of them). Preemptive text words are offered while texting to shorten the time it takes. Siri is supposed to open by simply saying "Hey Siri". And a load of other stuff I haven't even touched yet. I love it. Its like having a whole new phone again.
