Can I sort all the apps on my i-phone into some kind of folders?

[WhereTheWildThingsWere]

And how?

Yes... Hold finger down on one of them so they go all wobbly... Pick it up and drag it over the top of another app and let go... They will then be in a folder together... Continue.

Thank you.

What about when I want to merge stuff that is on different 'pages'?
