I have just recieved an unlock code for my Blackberry Tour 9630, and noticed that when i turn off all network connections and go to Options>Advanced Options>Sim Card and type in MEPD nothing comes up telling me the status of my device i then type in MEP2 and still nothing. I have done it with and without the sprint sim card, i have also done a couple of battery pulls thinking that may fix the problem but no deal. Although when it does have the sim inside of it it says "SIM card: Security Disabled" I have driphters v12.1 hybrid, anyone think that may have an effect? please get back to me asap. i will go ahead and attach photos of the screen with and without the Sim.
