Changing parts between 4 and 4s
I was trying to fix my oldie half alive iphone 4(it is locked with the passcode which I don't remember, been a long time haha) , changing some parts from broken-screen iphone 4s.
1) Is it okay to do it ?
2) Is it possible to change something(i don't know which part it might be) where the information about this phone is held(passcode etc.)
Thanks for answering!
Is this a good question?
