Hi,
I looked at the site using the tools I have available.
For the pda screen I used firebug with firefox to change the html on the fly.
The logo was too big and, as you described, the menu was obscured by it.
I found that
<img width="333" height="50" alt="Injecting Advice" src="http://injectingadvice.com/templates/mobile_iphone/mobilelogo.jpg">
shrank it enough. (Original height was 93).
When I tested it, I was seeing the xhtml/pda template instead of the iphone template. I used an iphone user agent switcher.
(If that sounds like gobbledegook, search this forum for "user agent switcher". If you don't find anything, let me know and I'll give some references.)
I tried testing with iBBdemo2 (an iphone emulator) and got the same xhtml/pda template so I do not know what it looks like with the iphone template.
I do not know what effect the google analytic plugin is having.
