IPhone stolen, has a PIN lock, can a thief access my data in any way?

IPhone was stolen last night and I have a PIN lock on it. Is there any way at all for the thief to access my data bar guessing the combination.

It would take a Really long time for them to guess the combination. They could just reset the whole phone and it would be like new and they could use it. You should:
1. Report the phone missing
2. Cut off your phone plan
3. Try to track you phone. You can go to these websites where you enter your cell phone number and it will give you an address.http://www.numberinvestigator.com/xxxyyy
