This is crazy, I finally decided to use the 2.1 rc to fix the ios 6.0 compatibility !#%&! and my app has stop working.
I'm not using native packaging or similar, I was just referencing the sencha-touch-all-2.0.js and replaced it with the 2.1 and now I get a white screen with no error log after the launch image.... ¿is there anything necessarty to use the 2.1 js ????????????
