Can you put folders into folders on the iPhone?

For example I have a folder full of browser bookmark widgets on my iPhone but I want to arrange them into categories and put them so they only are under one collection widget. If I can't is there an app for that?

No. The folders are new and designed to organize stuff into them, they haven't made it so that you can put other folders into them yet.

I hav enot seen an app for that but there may be one under lifestyle or business and finance. You can't do that on the actual iphone unless you are using photos application
