I could only test the "online" version of this excellent tools because I do not have a Blackberry but an HTC Win Mobile 6.x.
It's great of course and I appreciate this particularly useful tool when outside on the field, there where it is needed and not at home before leaving for a shooting day...
Why not extending this application to other devices like i.e. the HTC ? I would use it much more often than now because today I have to pay the "Edge" connexion costs of 3G !
Thanks anyway for sharing in the spirit of Nikonians...
