this is the manual way of doing it (i hope your listening very carefully LOL!)

d600, copy numbers from phone to sim. get an UNLOCKED 3g phone from somewhere and insert tmobile sim, and copy numbers from sim to phone. do this until all numbers are stored on the PHONE MEMORY on the unlocked 3g phone. get your new 3g sim card, put it into the unlocked 3g phone and copy numbers from phone to sim. then put your new 3g sim back into the new nokia youve got and copy numbers from sim to phone.

when your new 3g sim card changes from it's initial number to your tmobile phone number im pretty sure it wont affect phone numbers on the sim. BUT, as a safety net, as ive stated above, get your numbers on the PHONE MEMORY of your new nokia just incase.

simple (lol)
