Actually, Android 2.2 does provide some security measures for applications installed to the SD card. The "Move to SD" feature only moves the signed APK package. The package is encrypted with a randomly-generated key that remains in secure storage: http://android-developers.blogspot.com/2010/07/apps-on-sd-card-details.html http://android-developers.blogspot.com/2010/07/apps-on-sd-ca... This is not perfect copy protection (nothing is), but it protects apps against tampering by other apps. But it also means any files outside of the APK cannot be moved completely to the SD card; those files remain in internal storage. This is why apps with native libraries (like Opera Mobile and Google Earth) still take up so much internal storage even when moved to SD. [The "apps2sd" feature found in some unofficial pre-2.2 ROMs like Cyanogenmod does not provide the same security features. Your criticism is accurate in those cases.]
