If you own a smartphone (ex Android or iPhone), try accessing the site through it and see if the new smartphone-friendly theme works. There are still some issues (ex. search page doesn't have a search input field) but hopefully I'll be able to address that in the short-term.
Good stuff man. The link back test works for me on my iPhone 3GS with iOS4. The issue with the home link is that it just adds index.php at the end of the current page address it does not revert back to the root.
