The lock code should be the last 4 digits of your phone number or 0000.
If that doesn't work, perform an activation by dialing *228 send. Then select option 1. After this is complete your phone's lock code should be reset to the last 4 digits of your phone number.

OMG my phone is doing that too.... i believe that you can take it to your Cell phone service provider and have them unlock it for you. to do this you must go to a technician. the problem that happened was that i knocked my phone off the network so basically its usless at this point so i will need a new phone unless they find out the code so if they cant fix it your going to have to get a new phone

try dialing #43574357* it should show you the sid meid min etc. make sure you write down SID. then go to settings from the main menu>press *>587846. in the MIN and MDN field put in 10 digit phone number and put in SID exactly the same as you wrote it down so if 0 is the first number be sure to put 0 and the rest of the numbers. the phone will reset and your phone WILL work
