Christmas present ideas for a teenage girl?

Hi I'm 13 and i need some ideas for christmas presents. I like girly stuff but not too much. I'm more of a "hipster". I play basketball and do karate. I love music and makeup. I already have a lot of makeup on my list so I need different ideas. I already have an iphone, macbook air, nintendo ds, wii, xbox, and ps3. My preferred price limit is about no more than $100 and preferably around $50. Stocking stuffer ideas would be great also.

Can i buy an iphone 5s using cash?

I'm only 14 and I wanted to buy an iphone 5s with the money I've saved this black friday. The thing is I have an android that I'm giving it to someone for a really good cost. My old phone is not paid yet and its in a 2year contract and its in a family plan. My question is, can i buy an iphone 5s using cash at the store without buying any plan and stuff just the phone. And not even buying a sim card cos I'm going to use my old sim card.

My iphone is saying that i haven't bought music that i bought a while ago?

Well when i updated to ios7 i had to delete and re download everything i guess i didn't notice until now that not all my music re downloaded.well so today i was listening to music and i was looking for a specific song and i realized that it wasn't there so i went to itunes (on my phone because my computer's broken) and it said that i hadn't even purchased a ton of the music that i purchased in the past. And i don't want to have to buy it all again because it's like 100 something songs that are doing this and i can't do anything about it from the computer because like i said before, it's broken. So i guess what i want to know is do i have to repurchase it all? Or do i have to wait until my computer is fixed to do something on there? If that, then what do i do?

Iphone 5 unable to connect to internet

I've had this phone for about a year, and it has never given me a problem. But as of three days ago it is "unable to connect to the internet" my computer and ipod are working so I know its not my router. I have rebooted the phone, checked airplane mode (off)… It still won't connect.

I can't open videos on iPhone in any apps?

I just synced 5 videos from iTunes onto my iPhone. They were taken with my camera and I was going to upload them to Instagram. When I got to the app and tried to select the videos, they didn't show up. All the videos before them that were taken with my phone show up but not those. I tried opening them up in other apps too and I can't select them. Does it have to do with me syncing them? Or something else?
