IPS 4.X is responsive, so the need for a separate mobile skin goes away. We'll be upgrading this year, and it will provide the foundation for many exciting new features that we've been promising for years, so I'm pretty psyched.
You can preview how it looks, more or less, @ https://community.invisionpower.com/topic/217868-the-world-cup-2006-thread/
You'll notice that on phones, you still get first / prev / next / last, BUT you can also click on the "Page X of X" and go directly to a specific page.
After we upgrade the forums, we'll also be upgrading the whole site to be responsive... that should also be this year, so it's going to be a very busy fourth quarter for yours truly!
