Hi lisavelgrave! I'm sorry we didn't get this handled for you before you left New York. You can find details about the eligibility requirements to request an unlock for your T-Mobile iPhone here - Unlock your mobile wireless device. Essentially, it's a checklist. If you meet those requirements, you'd simply Contact Us and we'll file the request for you. Just a heads up - iPhones are unlocked remotely by Apple, so once we've verified the eligibility, we shoot a request to them and it does take a few days to complete, at which point you'd connect your phone to iTunes to complete the unlock process. Best wishes for safe travels!
