Just unlocked AT&T iPhone 5, but do I have to restore?

[BlueMoonForever]

I processed the unlock code through AT&T, and they sent me an e-mail back saying the device can be unlocked. They want me to restore the device through iTunes. Only problem is if I do this, it will restore to iOS 8.1. I want to stay on iOS 6. So my question is do I have to restore, or can I just pop in a T-Mobile sim card into the device now?

Why don't you just pop it in and see what happens?

Don't have an active T-Mobile sim yet. I am just wondering once AT&T unlocks the phone, if its done based on IMEI.

I don't think the sim has to be active. Just pop it in and if it says invalid that means still locked. With the iPhone 5 you will need to do a restore.

I shouldn't have to do a restore. That's BS because if I do it will load iOS 8.1 which can't hold a candle to the performance of iOS 6. I also do not want that bright fruit salad look.

I will have to test this out. But if I do have to do a restore in order for it to be unlocked, that's some BS!!!

I know that my iPhone 6 did not require a restore all I did was insert another carrier sim and waited for activation and then got signal. I think while back my iPhone 5s didn't require a restore either.

Try a friend or other family members T-Mobile or other sim to confirm. I think it should work without restore. It did for me when I got my 5 unlocked through att.
