Which one? You want me to read the whole review and list them out for you?
For that matter, there are a ton of sites with pretty detailed lists of iOS5 improvements over iOS4.
@waloshin: Awfully vague question. Which specific things are you curious about?
Are you here just to complain or do you have something useful to say?
Edit: Reading your last post, nevermind. Nothing useful.
Because we still have the same finger size. Not gonna happen until the screen is physically bigger.A) Then frustration and practicality set in. Why are there more pixels if I can't see more stuff on the screen? Why are there the same same seven rows of text messages and eight rows of items in the iPod app I saw three years ago when there are four times as many pixels?
You already have the option to change font size and number of lines in the email preview. Been there for a while.B) Only having five emails simultaneously visible is a shame on this screen. At least give me the option.
Some GPS with turn navigation are free on the App Store. Also, Apple is working on their own integrated solution. Not in iOS 5 though, hopefully in iOS 6.C) The alternative? Fifty bucks for an app. I don't have fifty bucks. Not for this ****. Especially not when my normal car has navigation. The iPhone has been capable of turn-by-turn directions since the 3G added a GPS chip. It's time for a better solution—from Apple.
