I'm a newbie to the iOS world, so my question will most likely sound dumb. Sorry. I bought a 64gb iPhone SE a couple of weeks ago because it was 99 cents on contract. When I received it, I created a new Apple ID acct and started using the phone. Yesterday, I bought a new iPhone 7 from Best Buy because it was $1 on contract. Since I have no intention to switch to any other carrier and my current grandfathered plan works just fine for me, I do not mind having to renew the contracts on these two lines for another two years. Anyway, I just picked up the iPhone 7 from Best Buy. It's already activated and voice/text/data work just fine. My intention is to hide this iPhone 7 and give it to a family member for Christmas next month. I do want to test the phone out, just to make sure there's nothing wrong within the return period. Can I just use the same Apple ID acct that I already created on the iPhone SE? When I give the iPhone 7 to the family member, can the phone be reset to factory default and another Apple ID acct be created?(as if it's brand new out of the box?) I don't want the iPhone 7 to be permanently tied to the Apple ID that I created on the iPhone SE. Thanks for your help!
