This seems to be the multimillion dollar question for Blackberrys and here is how this works.
There is no "magical"code for all BB's
Each Blackberry is item specific based on your IMEI which is located on the inside of your battery compartment.
Your best bet is to go to eBay or similiar and find your blackberry and look for the cheapest unlocking program. AT that point you will be able open your Blackberry.

Dear Carol, puk code can be found at your sim card package usually written on small paper in your sim card bundling when you bought that phone at first time. However if you can't find that you can call your provider and asking them about your puk code and it's free. That code can be used to unlock blackberry 8700 password and prevent your sim card blocked but you will lose all your previous data in after your blackberry unlocked.

I have an iPhone 4 and recently purchased a Blackberry 8700 as a back up replacement phone. Can I use the sim card from the iPhone in the Blackberry 8700? If so, how do I insert it?

You can't because the iPhone 4 uses a new type of sim card called "Micro SIM" and it is too small to fit into the blackberry.
