Hello,
I've download ios 9.3 beta. After that it started asking to activate my phone. It says someting like that "This iPhone is usin an Apple ID (it writes my id). To set this iPhone, use first id that used for first settings. This is stupid. Because I'm the first user of this phone and the first id for this phone is mine. If you have the same problem, please help me. Because I can't open and use my phone.
Thanks.
