Which Windows Mobile phone driver cab file should I install?

1. Touchscreen or non-Touchscreen
   If you interact with the glass screen on your phone using a stylus or your finger, then you have a Touchscreen phone. And if you don't interact with the glass screen, then you have a non-Touchscreen phone.

2. Professional or Standard
   I f you have a Touchscreen phone, then your phone uses Windows Mobile Professional. If you have a non-Touchscreen phone, then your phone uses Windows Mobile Standard.
