My name is Jocelin and I need serious help with an urgent situation. I'm an American grad student, currently based in London. My British phone--with all my photos, professional contacts, etc. was stolen today in NYC [yes, I should have backed this up in icloud, *that part* is my fault]. I'm in doc film, so a lot of that was very much not inconsequential. Apple has been completely and totally incompetent. Their iForgot program takes three days to even confirm whether they can get the phone in Lost Mode at all--I'll have to risk not flying, missing my exam, and potentially failing out of my program depending on whether my professors are understanding about this, which varies. I could possibly lose my visa. I'm looking for someone to help get ANY of it back, so I can move the data to a new device. Let me know if you're interested?
