I'm new to Android and have been reading some posts regarding installation an app. However I'm still puzzled about the installation directory. I'm using Desire and when I install any new apps, it seems to me that all apps were being installed to the /system/app folder. If not, they have been installed on the ROM instead of the SD card. Are there any chances to install apps on the SD card? Or how to move installed apps to SD? P.S. Is root the only solution? Thanks in advance.
