I wonder if I can set my GMAIL on my Blackberry 9670 asked if you want to sync contacts and calendar I did and it seems to download the contacts and calendar as well, as well as make contacts and calendar created in my Blackberry to my Gmail. But when I can alter my Gmail contacts / calendar, or make fresh entries that do not seem to be pressed to my device. I remember in the past was full two way synchronization. Am I missing something? For now I'm using the Google Sync, but I hate that my computer can natively support 2-way synchronization is not used.
