That is good to know AWA and thanks for passing along my feedback. I have since learned that the reason when I select Mobile Safari 3.0 as a user agent in Safari your site returns the messsage about using a version earlier than 4.0 is because Safari appears to incorrectly report version 4 when version 3 is selected. I tested with the correct user agent for 3 and here is the updated findings:
Version 3.0, 2.2.1 & 1.1.4 - all pages load fine, except for Campaigns tab where the top of the page loads fine but the rest of the page is just grey where all the campaigns should be listed.
Version 4 - Not yet supported as message indicates.
