I was recently going through some old stuff in my bedroom, and I found my old iPhone 4s. I was really bored, so I went on this IMEI tracking website to see the history of the phone. Much to my surprise, It actually said the phone was blocked from all US carriers because it was stolen. The only other owner of this phone was my mom, who used it for a few months after I upgraded. I got it brand new from an apple store, so thats the weird thing. My mom doesn't even know what an IMEI is, and I never reported it as missing or stolen. Why is it blocked then? Any tips?
