IPhone problem - music keeps deleting?

I just bought my iPhone 5s yesterday. I took it home, backed up my old iPhone and then put my new iPhone through so all the stuff on my old one would be on my new one. So far I've been able to download the apps and put the music on my new phone, but after I synced it with the computer the songs in the music app keep deleting themselves. I keep having to download them again (not purchase them again, take it from iCloud) through Wi-Fi off the iTunes Store, and some of them are even "unable to download now". When I go onto the settings when I'm on Wi-Fi I can "show all music" and then my entire I tunes library will appear, even music that wasn't on my old iPhone, but when I'm not on Wi-Fi everything will disappear and it will direct me to the iTunes Store. I'm so confused and I don't know what's going on. I'll give 10 points to the first who answers!

My iphone's power buttons is faulty, will I get my phone replaced?

My first iphone 5, a month or two after purchasing, had a really unreliable power button (on/off button), and the woman at the apple store decided that it needed a replace. 8 months afterwards, around a few weeks ago from today, I realised that the iphone I was given as a replace also had the same problem, and that sometimes it works and sometimes the screen won't switch off. My warranty expires in a week or so. Do you think they will replace my phone with a refurbished replacement or will they forced me to get it repaired?

How to make a digital photo look older?

I found the image (link posted below) online and I really want to figure out how (if possible) to make digital photos look sort of old like the photo I posted the link to. To me, it kind of looks as if it was taken many years ago but it is not "vintage". If it looks this way because it is simply a film photograph, how would I go about making a digital photo (pictures taken with an iPhone, etc) look like this image?

I'm 14 and a guy should i get the white iphone 5c?

Right now i have a motorola electrifyym and us cellular is getting the 5c and the 5s next week. I have heard the sales on the 5c aren't that great and i hope they don't stop making them cause that would be embarrasing to have a phone that sell but my parents can't afford a 5s for both my sister and i so we're getting the 5c. The reason i want it is because there's a lot more space on it, i like the looks better than my current phone, also i want to store my music on there and movies so its all in one place instead of on my ipod, and i really just like the built in apps on it. I like the blue but i think the white is more suitable for a guy (what do you think). At first i didn't want it cause it looked like an ipod and i didn't want it to be thin like one. BUT ITS NOT cause i went to look at it today and its thick and the exact same size as the 5s. Its sturdy and really well made. I also want an iphone cause i can buy a lifeproof to go on it. What do you think? Is white okay for me? Would you buy a 5c
