This should work for most Samsungs from what I've seen posted. 1. Turn off your phone, put in a SIM of a provider that it is not locked to, and turn it back on. 2. At the wrong card message, type *#9998*3323#. A message will pop up telling you to press exit, so hit the right softkey. Choose number 8 work, I think). Your phone will reboot and your SIM will work. 3. Type *0141# and then hit call. This will give you a message saying your phone is personalized. 4. Power down your phone and insert a SIM card other than the one that is in it. Power back up your phone. 5. At the SIM code prompt type 00000000, that is 8 zeroes. Your phone should now be unlocked. At least mine seems to be. Let me know how it goes. By the way, I stole all of this info from the threads below. I just kinda smashed it all together.
