Unlock iphone bought after Jan. 26, 2013?

I bought a Iphone 5 from T-mobile a month ago.
I heard that is illegal to unlock your iphone that is bought after jan 26, 2013.
T-mobile say i can unlock my phone after 40 days from purchase date, and it had been 40 days.
So, does anyone still do iphone unlcok that is purchased after Jan 26, 2013.

Don't unlock it

I got mine done at iPhoneUnlockedCheap.com
