Is your customer's device running Android 2.2 or above? If not, then you cannot install to SD.

Have you specified android:installLocation in your manifest? If you do not, then by default, you can only install the app to internal memory regardless of Android version.

See Android dev - manifest for general info, and Android dev - installLocation for more detailed information on the installLocation tag including how to maintain backwards compatibility.
