After 50 iPhones Unlocked
As of today, I unlock total 50 iPhones for my friends and co-workers. I want to share 4 unusual situation with you guys.
All 50 units unlock successfully.
One iPhone battery has no charge out of the box. And it turn out the battery drain out faster then the other iPhones (If you got in to this situation, you should return to Apple store b4 you try to unlock)
Three "Brand New" iPhones already has Activation file under /var/root/library/lockdown/ (You need to remove it to make youtube works.)
Just my 2cents
