I need confirmation ...

If a user has a BES BlackBerry device and an iTouch / iPad and both devices
are Email sync to the same GroupWise account, possible conflicts ?

I think BES is listening events on Port 9000 and retreive on Port 7191 while
DataSync is listening on Port 4500 and retreive on Port 7191.

Do you think that is possible to have the BES coming first are get the new event and
the DataSync not having any new event or the other way around ?

OR both will have their events, no possible conflict ???
