T-mobile Unlock Code Needed For A Siemens CF62t

Hi. I am a Cingular customer and no longer have insurance with my plan. So the last time my phone broke I was unable to use my service. My uncle gave me a Siemens CF62T that he had as an extra phone, however, it is connected with T-Mobile. How can I unlock this phone so I can use my Cingular service? I tried asking for an unlock code from both T-Mobile and Cingular and both refused.

I continue to enter *#0000*12345678# to unlock my phone and it does nothing but flash "Please wait".forever. Can someone help me unlock this phone?

u can unlock it with cable, but since the phone is from ur uncle, i presume u dun hv it either.

the other way, is to ship it out for ppl to unlock for u...around $10 (check ebay: unlock cf62t)

or since ur uncle gave u that, he probably still using tmobile, hv him call in
n request the unlock code using his acct.

good luck
