Tear and google plus: with the default user agent, google tells me that the browser is unsupported. If I spoof the ipad user agent, it redirects to the mobile site which doesn't work. If I spoof the firefox 5 user agent, google plus works (it's slow but it works) but I lose the ability to scroll with the d-pad in google reader. Restore the default user agent and the d-pad works again.
