I was at the t-mobile store yesterday..They called customer care.They told me I would have to pay the remaining balance,before they can give me my passcode.Just to unlock my phone for a different carrier.

so what is your question? and they are correct..you want to move onto another carrier the current phone you have will need to be free and clear of any payments etc..
