How to unlock an iPhone 4 to work on Cincinnati Bell?

I recently broke my Blackberry and think I'm going to get an iPhone 4 running on ATT and unlock/jailbrake it to work on CBW. Can you show me a website/directions on how to do this?

Not sure if ya can

That's no problem since AT&T and CBW are both fully compatible GSM carriers. The only thing you will need to do is to get your iPhone factory unlocked at one of the big online unlockers like http://www.cellfservices.com/ or at a local phone repair shop.
