I added a modification to the forums that give me alot more control of the mobile site (and supposedly it will automaticly pull it up on the iphone, needs some testing.)
I have it pulled up on my iphone now and its alot nicer than using the old theme, but I had to manualy pull up the mobile website (already had the forums pulled up before I added the mod).
So if anyone can give it a test with an Iphone, Droid, Blackberry, Ipod Touch, or any other mobile device and let me know of any issues. If it doesn't pull up the mobile site automaticly you can click on the WAP2 link at the bottom of the page (below the Powered by SMF 2.0).
Let me know if you use the mobile forums, and if you'd like a mobile version of the actual website.
