I have 2.2 on my Orange Desire, but I've never understood folders. Starred, phone etc seem to just give me the same list of people I get when I press the Phone button that's at the bottom of the screen. And I can choose 'new folder' and drag things in, but there's no way of seeing what's in the until I click on it, so if I have more than one folder on a screen it gets confusing and I have to look inside it first. It seems like a bit of a badly thought out system. Wouldn't it be good if you could see what was inside before you clicked on it - or perhaps if you held your finger on it you'd get a preview, or something? Do you guys use them, and if so - what for?
