After upgrading from Sencha Touch 2.0 to 2.1, I am facing the following problems in both the web app and the mobile app:

1. Web App:
After opening the web app on the iPhone browser, if I click on the icon to add it to the home screen and run it from that icon, it gives a white blank screen. The app otherwise works fine, if I open it using the url on the browser. Not able to find out what could go wrong with the web app if I open it using it's home screen icon.
2. iPhone app:
I use phonegap for both the android and ios versions of the web app. Android mobile app works fine on an Android phone or simulator. However, the iOS app just shows a white blank screen after the splash screen.

Would really appreciate any help regarding this.

Thanks
