I got an e mail from "Apple" saying that there is a problem with the upcoming activation of my new IPhone. I called the number but didn't give them any info bc I didn't feel it was legit. The e mail did contain and activation number which I did give them most of. They sent a follow up message containing my cell number which they likely got from caller ID. Has anyone heard of this and should I be worried that I called them? I didn't think it was legit bc the phone was already activated... And wouldn't my carrier contact me about activation?
