Hi, there. I dont know where the other thread for unlocking 6670 nokia phones are, so I am sorry to start a new one, either way Im pretty sure codes are exclusive to phone. I need some help, I lost my SIM card and bought a new one. To my surprise my phone is now asking for a LOCK CODE that I dont remember activating. I tried the default to no avail. I also tried to download the software available but it does not not work seeing as I have a Mac computer. Can anyone help me? info on back of phone Nokia 6670 Fido Type rh67 Imei- 356666001870086 Netwwork: Fido (owned by Canada Rogers AT&T) MCC MNC 302-370 ? Code 0520930 Any help would be appreciated, thanks. Ps: Disregard the next posts, im a noob here and dont know how to delete posts, sorry.
