Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do what I can to provide the right answer to your question.
Please let me know, was your iPhone insured in any way? or was it a company iPhone, or otherwise 'covered' ?
If the iPhone was covered by your company, or by insurance, you need to contact the company, or the insurance company, to
A. report the loss in a systematic fashion: when it was lost, what circumstances or location, roughly, and model or serial # ***** if you can find it.
B. put in a claim for replacement, reimbursement, or whatever can be provided under the coverage or policy.
