You can set up your sync however you like. I have mine sync to Entourage contacts at home, and Outlook Notes at work. Just alter you Syncronization Settings through Desktop Manager.
As for syncing with your mac you will have to open up pocketmac and do the same thing. Just uncheck the settings you don't want to transfer.
I am not sure about your other question, but I don't think so. Others here may know.
As for the format of the number... It's all how you put it in your phone. No way that I know of to set the format.
it's the right time to crash, is it not?
