Activation lock iPad air
Hello everyone i was wondering if use could set my mind at ease. I bought a second hand iPad Air from eBay it was only local so was able to go round and collect it on arrival I looked at it and it was like new so I was over the moon as it was a replacement for my daughters old tiered iPad 2 which had finally given up. The guy erased the iPad for me there and then in front of me I dashed home to set it up to find out about this activation lock I was gutted. Anyway I drove back round and the guy put his username and password in and we set it up as a new using my daughters username and password but he didn't turn off find my iPhone as he only put his details in to remove activation lock. Does this mean it is now not associated with him or is it it a case if I have to erase the iPad will it need his details in again ?
cheers
