Option # 3: T-Mobile or Cingular, your carrier
Yes, you can ask your carrier for an unlock code for your Blackberry and guess what, they do it for it Absolutely FREE. So, what is the catch? The only condition which atleast T-Mobile imposes on its customers before it gives out the unlock codes for the Blackberry Pearl or any other cell phone is that you have to be under the contract for atleast 90 days or 3 months before they can give you the unlock code. So, if you have the patience, I would recommend that you wait for this 3 month time frame before calling up 611 from your T-Mobile phone, talk to customer service and get your unlock codes.
In my search for the Blackberry Unlock codes, I found out that a lot of people mess up before they have no idea how to enter the unlock codes correctly. So, follow this method to enter your Blackberry Unlock code
