Best place to unlock a Tmobile iPhone 5

I am looking to sell my iPhone 5 and looking for the best place

I went to ebay but all i see is unlocks for the AT&T one .... Can you guys show me to a cheap website that does this for the tmobile one

Never got it unlocked just sold it to someone that needed it, but i also heard a Tmobile store can unlocked it for you if you have been paying its plan well in the first 2 months and thats free. You can go and ask to see if they can do that and that will be free
