Question about iOS Betas - do they expire?

Yes they do. Beta 1 expires in Jan 14 if I'm not wrong.
Anyone knows when Beta 2 expires?

 

i thought i read january 28th or something like that.

 

What happens when it expires and you don't update?

 

Yep

 

Just remove the beta string in /system/library/coreservices/systemversion.plist

Beta won't expire then.

 

The phone gets locked out basically to where you need to restore to the latest official version or perhaps another non-expired beta.

 

GM is effectively the released version so that's why you had no issues with iOS 6 GM. Betas do expire and will lock you out. Beta 1 is Jan 13th and Beta 2 is Jan 27th (so I read somewhere).

 

This, I doubled checked with sn0w about this too;

So as far as I understand, by editing the plist, the 'lockdown' (which is constantly checking) will never check for the beta expiry date.



Can someone tell me what happens when your dev account expires though!? Will that terminate the beta firmware on the device? I can't believe it does as it can't be any different to when they stop signing their firmware surly?

 

The next time you install or restore a beta update that does an activation check you'll get locked out as not being part of the dev program.

 

Right but if you jailbreak and remove the expiry, I.e the beta last forever and the dev account expires - nothing will happen? Pretty much just like any other ios firmware that apple stops signing?

 

Correct
