I see that you are a BB7290 and ACT 6 user....
I have a 7290 and also use ACT 6.0. Since the 7290 will only hold about 2,000 contacts, have you found a way to only sync certain Groups from ACT? I have over 18,000 contacts in my ACT database and only want to sync 1 particular group that contains about 500 contacts.
I have found and am using a very nice 3rd party software "CompanionLink" that allows me to select which Groups to sync from ACT but does not Sync the Calendar. Are you aware of any 3rd party software that allows for selective Group sync AND sync's the Calendar?
Thanks for any help you can provide.
