Does upgrading to iOS 7 beta 3 make you lose a GSM unlock?
I'm using AT&T GSM 16 GB iPhone 4 currently running iOS 6.1.2
Added (1). If it does make you lose it, is there anyway to get it back?
Added (2). I have a factory unlock through itunes, not a jailbroken unlock
Added (3). Well i unlocked and i'm definitely using a factory unlock that i had to pay for and then unlock through itunes, so you are saying my unlock should not be affected?
Depends if you have a factory unlock or a jailbroken unlock such as Gavey sim etc.
Well if you brought a factory unlocked service you shouldn't lose it but if you have one of those gevey sim unlocks then you will and you might need to unlock it again depending which gevey sim your using! I know neter gpp support ios 7 beta.
No, if the unlock is legitimate then you don't have to worry. However, you do need to make sure your device's UDID is registered with a site like http://www.instantudid.com/ before you install the beta. Otherwise, Apple has been known to disable devices that try to use the beta firmware without being registered in the developer program. I registered my 4S there and I haven't had any issues.
If it is an iphone factory unlock then it is permanent. Even if you reset, restore and upgrade its ios, the unlock won't lose.
