BB Connect 4 don't works on Asus PocketPC ; I have an Asus P750 and I have tested BB Connect 4.0.87 , 4.0.92 and 4.097 (the last) version without success (I have a Vodafone Italian Sim with a BB Data Plan).
The BB Connect software works correctly but the RIM Server reject the Asus Device and don't send the PIN Device because they not have a partnership with Asus .
Asus don't pay the royalty for to use the BB Connect software and service.
