I am new to Blackberry, just changed from Windows Mobile 6.5

1. I am looking for cloud solution for MS Outlook (Calendar / Task) that is able to work with my Blackberry Calendar & Tasks only. Having contacts all together would be good. I just want things fast.

Reason: I cannot sync data while amending data (while connected to my PC). This doesn't happen with my Windows Mobile 6.5

Question: Are they are solution for this?

2. I cannot cut & paste appointments

Reasons: I shift my appointments time to time. It's very fuss to change 1 simple appointment by selecting a time. I could do that in less than 5 seconds using WM6.5 compared to 15 seconds under BB6 (I need to look for empty time slot!)

Question: Are they better calender apps that can allow me to do this?

Google Sync, perhaps?

Not sure exactly what you are asking in number 2. Can you elaborate?

Have a look at Welcome to WebIS.net - Pocket Informant BlackBerry
There are not so many options for calendars on BlackBerry as most users like it the way it is. The prime directive for the BlackBerry calendar is Outlook integration.

Another option is to join a service that provides Blackberry Enterprise Service for calendaring and email in real time.

Hope this Helps,
