ITunes playlist and certain songs won't sync to iPhone?

So i added some songs to my iTunes using youtube2mp3.net and and i made a playlist and burned it to a cd but for some reason it won't play the cd when i'm not using my laptop because thats where my itunes is. But the same songs/playlist won't sync to my iPhone and i do have it checked off on my itunes so it should be syncing but its not. What is the problem?

Have you ever bought a iphone off ebay, Should I?

I wanted to buy an Iphone 4S off ebay for 422 dollars including shsipping. It has a clean esn and is in excellent condition and comes with everything although the phone is used for about 4 months. It still has warranty till Sept 2013. The seller is also including 4 cases. This seller has excellent feedback.

However I'm still indecisive and scared to buy off ebay. I could just buy the phone brand new for 449 free shipping and I get to keep my phone insurance as its prepaid with Virgin Mobile. The difference in price is not much. If I buy it new ill get to keep my insurance, have a year worth of warranty instead of 7 with the used phone, and I can return it if anything is wrong or I don't like it. Have you guys ever bought a iphone off ebay what's the better deal? I really like the 4 cases that come with the used phone it comes with box, charger, earphones n everything. But i don't know?

Why won't my iPhone 5 take pictures?

My iPhone won't let me take pictures, save pictures, or screenshot. I tried deleting pictures and I deleted over 800. I now know storage is not the problem. Each time I try to save a photo (usually from twitter) an error message pops up saying "Error; Write Busy". At first I thought it was a twitter glitch but then I realized I could not take pictures through the iPhone camera app, or any other outsider camera application.

On the facebook app it shows up fine but that app doesn't update all the stuf that the internet version does &'and it doesn't put posts in order from most recent!

Can you turn off 3g on iPhone 4s from Verizon wireless?

Some forums have said that certain carriers won't give you this option on the 4s. Can you turn it off on iPhone 4?
