I have created a simple guide for newbies to iOS 5. Feel free to help me expand it, and create more guides as the need arises. It can be found here; http://guides.macrumors.com/iOS_5_Primer
Great, thanks. Not sure if it's really my place to edit your guide (or any guide, for that matter) but I did want to try to help in some way so, to start, I'll share a "visual" guide to iOS 5 that I created in the iOS 5 forum:
Perhaps you, or others, can take images or just ideas from there and apply them to your guide. Or perhaps not. Either way, if I can help in any other way, feel free to let me know.
