How to remove Apple ID from an iPhone?

I bought my ex an iphone using my credit card & Apple ID from the Apple store. We broke up last week, so I took the iPhone away from here. Now, I'm looking to sell it & I won't be able to because the iPhone is locked with her apple ID. Since we don't talk anymore, she won't talk to me & doubt she will give me her password to unlock the phone. What can I do in this case to remove her Apple ID from my phone. I went to the Apple store & they said there's nothing they can do. Now, I just have a worthless $700 phone with nothing I can do with it. Does anyone know a solution to this issue? To remove her Apple ID from my iPhone.

How to Wi-Fi hot spots work/what one should I get?

Would it charge to my house bill? I have unlimited Wi-Fi at my home so would that matter? All I need it for is my iphone because my plan can't be updated until May, so until then I need a Wi-Fi source at all times while I''m without a data charge. My friend said he bought a Wi-Fi hotspot and never really uses his Wi-Fi unless he forget the hotspot at home.

Other than that what reliable hot spot should I get?

Finding someone with IP address?

Please do not judge me for my dilemma… Any help would be greatly appreciated.
Last night I lost my phone in a taxi cab in New York City. I got out of the cab in Brooklyn around 4:30 am to stay with someone I met that night at a bar in Manhattan. As soon as I got out of the car, I realized I left my phone inside. As the cab sped off, I decided I would just wait until the morning to track my iPhone and all would be well. The next morning I used the guy I stayed with's phone to track my iPhone but the phone read "offline". I only know the guy's first name, I don't know his last name. I have no idea where I even was in Brooklyn. This morning I did however use the guy's phone to access my email account. My gmail account is showing me the guy's IP address. Is there a way to find out where he lives from his IP address? The cab company can't help me very well if I don't know where I was dropped off. Someone please help me. I don't live in New York, I had to leave today, I have No money. I'm stranded in the LaGuardia airport with no money or phone. I realize I'm an idiot but if someone could please help me figure out how to find him I would be eternally grateful.

About a month ago I was at a friends house and theyg. It into a fight and he ended up throwing my iPhone out the front door. My screen was already alittle cracked but now it's about 60% worse that whole top corner is taken out, and my cameras broke. He told me he's not gonna give me the money to else it so I said I'm gonna file a police report and get it that way. My friend asked me not to and said she'll give me the money for it at Christmas. I never got the money and my phone is still broken. So is it to late to file a report against him, also is it worth paying the money to file?!
