its not my phone, it belonged to my sisters friend, but she gave it to me. I tried putting in a tmobile sim card in it and it said please wait to enter a passcode and said emergency use only. Do i need to get the system reset or something? What can I do so I can use the phone? it says please...

I want to know whether my samsung i450 or samsung beat 450 has inbuilt GPS antenna or not ? or do i need to use an external GPS antenna.
