You can sync almost as many phones as you want, you just have to make sure the sync names are unique for each phone. And you technically can have them connected at the same time, but they have to be using difference connection methods. For example, I have my touch pro to sync usb, and my mogul to sync with bluetooth.

This can be difficult to get working sometimes. I often tell people the easiest way to do it is just create a second logon profile on your pc for each phone. So if you need to sync phone 1, login with profile 1, phone 2, login in with profile 2...etc.
