I am trying to erase all the information on my phone but the phone is unlocked so that any carrier can be used on it. If I use the "erase all content and settings" tool in the phone, will the unlock erase as well?
iPhone 4, iOS 7.0.4
No
unlocked ,if done by the carrier or purchased unlocked from Apple when new is a fixed state
If however the iPhone was hacked to unlock it from a carrier then anything can happen
AT&T unlocked it for me through the phone, so does that mean I can go ahead and do it without the unlocking going away?
Correct it will remain unlocked
It now no longer shows as locked to AT&T on the Apple Activation Servers
If I use "erase all content and settings" will it erase my unlock too?
