Notes about Apps2SD : 

Unless specifically authorized by the developer, an app cannot be installed on external storage. So, until developers update current apps to include this authorization,  no current apps can installed externally.
Another important concern was making sure externally installed apps would not be more easily pirated. To address this, apps installed on the SD card will be encrypted in such a way that they can only be decrypted by the device they were installed with. In other words, if you remove the SD card and put it in another phone, the apps stored on the card will be unavailable to you.
Private user data is never stored on external storage, even if the app it is associated with is.
