Should I upgrade to iPhone 5 or wait for the next version?

I'm eligible for an upgrade with Sprint. It seems like iPhone models generally don't last too long before a newer version is released. I don't want to upgrade and months later a newer version come out. Any thoughts on how much longer the 5 will be the newest version and your opinion on if I should upgrade now or wait would be very appreciated. (Btw excuse my name I make beats for rappers lol)

Galaxy S4 vs iPhone 5 vs HTC One? - 1

My contract with T-Mobile ends pretty soon and I'm changing to AT&T, so my parents are buying me a new phone and gave me those three choices. I don't really care about the apps and features, but I want someone to compare the camera, speed, battery life, storage, durability, and call quality between these three phones.

I really need your help! My Iphone is pissing me off?

Ok. So apparently I used 6.0Gb already when I have NOTHING on my phone. I have honestly 2 apps and couple messages and pictures. I tried to back it up and it didn't really do anything. And I really wanna know what could be using up basically all my memory… I don't know what to do. I keep deleting like everything off my phone what can I do… I only have about 335MG left. I can't stand Iphones right now. Ugh.

How to transfer All my music from iphone to computer?

I reformatted my laptop and I lost all of my music that was on it because of it. The only music that I have for it now is on my iphone but i can't seem to get the music to transfer onto my computer. I'm getting aggrivated because i'm not going to buy a program online to transfer all of my music (606 songs) to my computer. The programs I keep finding from youtube or just a general search are all just trials that only move over 60 songs, 100 songs, 3 songs, etc. In the the trial version. I know how to transfer music from a IPOD by unhiding the files but obviously it doesn't work the same. I no longer have a Ipod. Thats why i can't just use that to do all of this. Does ANYONE know how to transfer music from the IPHONE to the computer?

Why does my iPhone keep skipping a certain song?

This is the first time that it has done this for an extended period of time; it has done it here and there but only once. I'll click the song (Cruise by Florida Georgia Line) and it just has the little play symbol at the top for a few seconds like it is going to play it, but then it just skips over it entirely. I just bought the song yesterday, and after I bought it off of iTunes, it played perfectly fine. I really want to be able to listen to it, please help!

Added (1). And if the file is broken, or the iPhone can't read it, how can i fix that?
