How to make 200 dollars quick. THIS IS Really IMPORTANT?

Last night, somebody stole my boyfriend's iPhone 4s right from his hands. We did all we could, but got no licence plate number of the thief, did a hard wipe of the phone at the Apple store, I tried texting the number but got no reply and there's still a year until he has an upgrade available. Seeing as it's Christmas time, I want to buy him another 4s. Fortunately, my friend Victor is selling his + accessories for 200 dollars. My mom won't give me the money, and I'd like to get it before Christmas. Only real answers please. Thank you so much, and happy holidays.

Kindle Lending Library without a Kindle?

I currently have an iPad, iPhone and read using the Kindle app for the desktop while at work. I also have an Amazon Prime account.

Nexus 5 or stay with iphone 5?

I've had an iphone for quite some time now and I'm looking to go for a nexus 5. There are some things that still bothers me. I'm very into having music on my phone as I have over 700 songs. I was hoping I could get those on a nexus too without any troubles. I also noticed using a friends android that music doesn't play as loud as the iPhones do through headphones. Which can be a problem for me. Also group messaging with my friends is a also very important as well as doing it quickly and efficiently. As well as the use of emojis. Another thing is battery life. Which is HUGE how do they compare to eachother. How's kit kat vs iOS 7.So if you could spread your insight of the phones with me it'd be greatly appreciated. Tell me if I should jump ship or stick with apple?

IS 1GB of internet/date enough for my iPhone 5s?

As someone who would rarely use my phone away from my home wi-fi system, would this be enough? I would have my internet turned off away from home most of the time unless I was using it to check social networking sites (eg. Twitter and Tumblr) for maybe 5-10 minutes on buses or at break and lunch at school.

Also, can you use iMessage on a normal network connection or does it have to be 3G?

How to un-flash an iPhone 4 back to verizon?

Hi, i have an iPhone 4 that was originally used for verizon, someone flashed it to be used on page plus, how can i return it to normal setting to be used on verizon again? I'm not interested in page plus. I'm very familiar with jailbreaking and ssh and how to get into an iPhone. I just don't know how to get the iPhone back to original setting so it can be used on verizon again. Is it as simple as a restore and then clicking "erase all content and settings" or is there more to it.
