[G4 Q&A, Help & Troubleshooting] Crazypinoy9:
The argument right now is that there should in no way be any restrictions from a carrier if the customer purchases a product at full value. Although, this restriction is technically included in their T's & C's.

BUT!!! In line with those same T's & C's, technically there's no way for them to stop any of us from having an existing tmobile customer gain an unlock code using their account as long as sed customer claims it as their own during the unlock process. After it's done tmobile can't do sh**.

What you are describing falls under their eligibility requirements for "Unlock eligibility for monthly phones, tablets and mobile internet devices". What I'm trying to do technically falls under the standard device unlocking requirements (IN RED). They can't tell a tmobile customer in good standing that they can't unlock a tmobile phone that was purchased for them as a "gift" that was paid for at face value as long as that tmobile customer meets all of tmobile's requirements pertaining to the unlocking category they fall under. If they do that then they're in for a lawsuit for sure...
