Re: "Like I say, there’s no user guide to tell you what all the icons means."
Alistair specifically said he couldn’t find one online, even on Apples website. Guess what the first hit on google is if you search iPhone user guide.
Many people won’t need this (hence no paper wasted in the box) but it’s useful for new features (like new gestures) or new users and is certainly not hard to find online. Oh and in the box, on the fold out quick start guide, is the URL for more support so I don't think there is any more than can be done here.
