I have been asked for a simple MVC example and I have created one (for this thread http://www.sencha.com/forum/showthread.php?161958). The examples that come with Sencha Touch 2 are great but a small, simple example is nice also.
This works with PR3 and I will try to keep it updated with each release.
**NOTE** I will not create a test app for everyone. I simply decided it was needed and this thread had a drawing and i decided to go ahead and do it.
