Thanks for your replies, and sorry for my lack of patience.
Actually I am working on XP.
As I said in the beginning, I am very satisfied with my BB curve. I used to have a Nokia 6233 before and synch was simple and efficient : synch via Bluetooth with Outlook 2007/MS exchange. Quick and easy.
I travel a lot in my job, so I need to have calendar and contacts perfectly updated on my device (no paper).
Since I got the BB, knowing that direct synch appears not possible until now, the only way I found yet is much more complicated : 1/ synch old Nokia with outlook/MS Exchange at work 2/ synch Nokia with mac at home using Phone Director, 3/ synch BB with mac using pocketMac. So I am sure you understand that I need to sort this out asap...
And it is very difficult to find any help doing a synchro with BB/Outlook 2007/MS exchange
Believe me I spent hours searching...
Many thanks in advance for all your help.
