I have updated to the latest version of Postnote (v2.0) and the iPhone version is still not switching to desktop version when clicking the switch icon.
ALSO
In my efforts to avoid this i set the iPhone version to default in the template params and to my surprise the main menu doesnt show correctly on iPhone (this could be the same on tablet and android but i dont have them to test). It shows only text.
If you want to preview this effect on my site go to http://cts.flux3.com
If i must endure another template update, that will be another few hours of replacing css and images afterwards so please be more in depth in your template testing before releases
