I can't find specific answers to some specific questions regarding unlocking. If I missed it, please point me in the right direction.
Just a few elementary questions regarding unlocking a carrier locked device. I know flashing doesn't unlock a phone. But you can pay $2 on ebay for an unlock code. What I wanted to know is:
a. If the unlock is successful and afterwards I flash the device with a custom rom, will the sim lock return?
b. Does the phone send any notification to the carrier upon unlocking? No point unlocking the phone only for the carrier to remotely lock it (if such a thing is even possible).
c. If the unlock is not successful, does the device retain any information regarding unlocking? If I do have to go to the carrier to unlock it, I don't want them going over the history of grey unlocking attempts. Also how often can I try before hard lock?
