Some songs won't sync to my iphone?

On iTunes on my computer, some of my songs won't sync to my iPhone even though they are ticked in the playlist and music library and both of them are set to sync on the iPhone part of iTunes. They all sync every time except the 5 or 6 that don't and there's no difference between the ones that do and don't sync. The songs that don't sync have been on my iPhone before but I download all from my computer iTunes, but when I don't like a song that is on my iPhone, I delete it from my iPhone so it's still on iTunes on my computer if I want to sync it again.

Any help please?

How to delete apps on a jailbroken iphone 4?

I just got an iPhone 4 from a family member and they had it jailbroken or whatever and whenever I try to delete an app they shake, just like they do on an iPhone 3G, but that's all that happens. It freezes with all the apps shaking and I can't do ANYTHING. Then after about a minute it appears to restart itself and the apps are all still there.Am I doing something wrong?

Trusted iphone unlocker? Does it work? Worth it?

I don't care about the whole warranty thing, but i would like to know if it is a scam. After i jailbreak my iphone i would be careful not to jump into scams or get hacked, but i wouldn't want to get a bug or get hacked as soon as i jailbreak my iphone

My iPhone is acting weird

So that's what happened

It all started when I was going into an elevator and my iPhone, as usual, lost signal. Now, when I went out of the elevator the screen went black for a few seconds.
The iPhone went back on and I realized that it shows numbers instead of signal bars(for example, right now it shows -97 next to the carrier name) and SBSettings won't work.
Tried to:
Respring
Restart
Power off/on
entering DFU mode and back on

Non of them worked.

Please if you know what to do, tell me.

Transferring contacts from iPhone 4 to Nokia Lumia 710?

My mom just bought a Nokia Lumia 710, and she asked me to transfer her contacts from her iPhone 4 to her new phone. I saw this video on YouTube about the "contact transfer" option in the Lumia 710, but it doesn't work. I tried it, they paired but when it says "transferring" or something like that on the lumia, it stops and doesn't work anymore. They have the same pin and *** but still doesn't work. My mom's paying me 1 per contact and she has 438 contacts. Lmao.

Why isn't my book on my kindle?

I downloaded a book for kindle on amazon.com.
I do this sort of thing all the time, and, pretty soon it's on the kindle for iPhone app, where I read them. I downloaded a book two nights ago, and have purchased it with enough money in my account and everything, but it's not appearing?
