[IS300T]

hey guys,
i just got the 16gb 3g iphone it has been activated previously. would the iphone work if i restore it with my 2g backup and just put my sim in there ?? or do would i have to unlock the iphone ?

I certainly would never restore to a previous back up. This method causes so many problems but it's your call. If it has been activated your sim should be fine.

the reason why i say restore is. my contacts,notes etc are able to be restored. but the situation described above will be able to work ?

If your on AT&T should not be a problem.
Here is a link to how you can SSH and recover your files and not have to sync from a back up. It is the preferred method.
