Have an older 5165 (TDMA I think) that I would like to unlock from my old carrier of Bluegrass Cellular in the USA out of Elizabethtown, KY. Is this possible and if so how would I get the IMEA for it, or is it needed? I know how to do the *#06# thing on newer phones, would that give me the same result on the older phone? I only want to know to make the phone resellable or donatable.
