Whatever I sim I put, it asks for a restriction code. I dont wana give it to the repair shop because they are gonna charge a lot for it and they r the ones who screwed it..They say it's because of some kinda memory or software loss :S..
Please help me with this. I want to unlock it real bad.

hi restriction codes is nothing but your mobile is locked to particular network so it wont accept other network sim .you can use codes to remove the restriction in your mobile .you can get the codes from here superunlockcodes here they ask the following details before providing the codes they are mobile model ,country and the provider to which the mobile is locked .finally they will ask the imei number of the mobile .and then they will send you the codes to unlock the mobile.

You can get the Unlock code from the service provider and unlock it from Network lock.
