Ask user if they want to see the mobile version of the page, redirect accordingly

Question

I just need to find out how to detect if the user is on a mobile device, and ask them if they want to see the mobile instead of the regular site, and redirect accordingly. Is there a non-PHP solution? Or a WP plugin?

Answer 2

Nowadays Responsive Design (here and here) is the prefered path to take.
Though not a direct answer to you question but this would be the path I'd take instead.

Edit:
If you want to do this in Javascript/jQuery you can ulitize Modernizr for feature detection instead of fixed browser detection.

If you want strict browser detection you can check the UserAgent and take appropriate action.
