The process of unlocking a phone is actually quite simple, and doesn't require any technical knowledge. There are three accepted methods for accomplishing the unlocking. For some phones, you just have to enter a numeric code into the phone. For a fee, some service providers will even give you the unlock code for your phone. There are also third party companies that provide cell phone unlock codes for a fee that ranges from $5 to about $25, depending on the model of phone you have.

I recommend the site Unlock-Zone.com which is nearly perfect and they were recommended highly in the cell phone forums. I used them to unlock my cell phone. contacted them and within 30 mins i had my unlock code and my phone was unlocked.
Hope this helps.
