Ever since I made the switch to IP.Board 3.3 I'm unable to view the board as "Full Version" from my mobile phone.
Whenever I go to the site from my iPhone I see the IPB Mobile theme. I go to the bottom and select "Full Version" and it just reloads the page.
The Fix:
1. Login to AdminCP
2. Look & Feel Tab
3. Template Tools
4. ReCache your Skin Sets
After that you should be good to go.
