Unlocking a locked logic board
I'm new to apple. I live in india . I've seen tons of youtubers buying iPhones (broken) from ebay and they make small changes like changing battery… and it starts working.i too would like to do the the same.
1)What is the difference between cdma and gsm
2)is it possible to use Indian sim cards in it
3)if the phone is locked to say Verizon, is it possible to unlock it and then use Indian sim cards.
Can you also suggest a few websites where I can get broken iphones.
Is this a good question?
