Permissions/Licensing questions aside, the icons in the Salesforce browser UI are all referenced through CSS styles. I have used them for native (Visualforce) pages, but not sure if you will be able to access the CSS remotely. Performance wise, I think it would be a better approach to use local images as part of your app.
I have a similar question - are we legaly allowed to use Saleforce icons? I do need an icon to use inside of native iOS app, but can't find any usage guidelines for it. Any resource on this please?

I would rather download them locally and use it in my app, if I can.
