I have a Sprint model iPhone 6 that was unlocked by Sprint and I had the policy changed on the phone from Sprint to Verizon. Once I upgraded to IOS 9 beta2, the phone reverted right back to a Sprint policy and Sprint lock as the activation server would not allow my iPhone to activate again with my Verizon sim. Anyone else having a simliar issue? Just wondering. I have contacted Sprint and Apple and both show that the phone is unlocked, however, Apple does see the change in the policy. I had an RTA submitted to the engineers so they can change the policy back to Verizon. I will post later on if this is a fix or not.
IOS 9 beta2 unlock wiped and policy change
The fix to this if anyone is having a simliar issue is by restoring your device using an Apple store computer with their iTunes. This will activate the phone and change the policy back to whatever you had on your phone.Hope this helps anyone else.
