I am very new to Sencha Touch framework, want to start with Sencha Touch 2.0 but not able to find any tutorial showing an application built using MVC Pattern and specifically in Sencha Touch version 2.0.
Here are two videos from the sencha 2011 conference:
SenchaCon 2011: MVC in Depth Part 1 https://vimeo.com/33311074
and
SenchaCon 2011: MVC in Depth Part 2 https://vimeo.com/33430731
Also you can check their blog for other short tutorials.
Another video to better understand Sencha Touch 2
