How to unlock a att inspire 4g for tmobile for free?

You have such a good mobile and you are asking for a free unlock code. You can ask the unlock code from the network provider. But i doubt you won't be getting the unlock code for free from them. Other than that i don't think there is any reliable service providing free unlock code. My advice to you is even if you get any free offers don't believe them. You have vulnerable risk to lose your mobile. Most of the free offers provide wrong codes. And If you enter over a certain amount of wrong unlock codes on your HTC Inspire 4G mobile phone, your phone may get hard locked and sometimes become unusable. Instead you can try through any reliable paid unlocking service. For example you can try Theunlockspot.com . This site provides excellent unlocking service.
