My iphone 4s was stolen yesterday. What next?

So yesterday I set my phone down and left it by accident and as soon as i realized that i don't have it anymore, I went back to retreive it. Unfortunately, some jerk decided to steal my iphone, which i really dont understand since it had a crack on the screen... I tried using the Find My Iphone app but the person who stole my phone turned my phone off, so the app can't track my phone unless it's on. luckily, I had a passcode on my phone. I know that there is no chance that i will never get my phone back, so i selected the option to delete all my data from Find My Iphone as soon as my phone is turned on. The REAL question is, what do i do next? I have insurance on my phone with Verizon, which i'm pretty sure, is called Asurion. I filed a claim, and now they're asking me to fill out

form/affidavit, complete it, and upload it to the website. If i upload the form, do i get a new iphone? will it be refurbished? Is it better if i purchase an iphone 4s from ebay? If i buy it from ebay, how does that all work? Help would be MUCH appreciated. I feel like now that my iphone is stolen a part of my life is gone. all my personal info, contacts, and emails.
