Song will NOT delete from my iPhone 5

My iPhone is driving me crazy! I have a song that for some reason has stopped playing - when I select it from my music list on the iPhone, it gets briefly selected and then skips ahead on its own to the next song on the list. Something was obviously wrong, so I wanted to delete it or at least reload it. I've gone into iTunes, deleted the song from both the Playlist and the Library, and synced my iPhone. It no longer appears anywhere in iTunes that I can find, but it is still on my iPhone even though it won't play! How on earth do I get rid of this thing! Thank you!

Added (1). BTW, I Can't swipe to delete - with all the other songs, the "delete" option comes up when you swipe, but not this song! It is really f'd up. I'm going to do the factory restore.

Is there any way I can turn on my Iphone 5 without activating it?

I ordered my Iphone 5 online and it it already came in the mail. I have had it for about a week but i'm not allowed to activate it until my siblings order their smartphone. If I activate it, I will automatically begin being charged for the data plan so is there any way i can play around with it or use it as an ipod until then? I have verizon and i know their iphones are sold unlocked if that makes a difference.

Thanks.

Added (1). Also, when i ordered it online, I already signed up for a data plan but they will not begin charging until I activate it.

Why isn't my iMessage working on my iPhone 4s?

Okay so my iphone 4s is currently running ios 6.0.1 and for the past 2 days my iPhone has been sending text messages in the regular form (in green) and the other person that i was texting had it turned on, so i checked if my imessage was turned on and it was but it said waiting for activation for hours.under it it said that there was no addresses to receive it at so i tried clicking my phone number but it was gray and didn't work, only my email works and i don't want that. I turned on and off my phone and reset the network settings but still it does work.

How to get my Sprint iPhone 4s factory unlocked for T Mobile?

It is iOS version 6.0.1 and I can pay some money if necessary. It must be FACTORY UNLOCKED though. Jailbreaking it and it getting it unlocked only will make it slow and could not be updated. It is a Sprint carrier, and I'm a T Mobile carrier, I just bought this phone from my friend because he got the new iPhone 5.

Why are one of my radios not receiving RBDS and one is?

I have a FM transmitter for my iPhone and it happens to transmit the name of the song over RBDS. When I have my cell phone with a radio inside it within about 10 feet of it it picks up the name of the song as well. My other Insignia Tabletop HD radio also has a RBDS (not to confuse with HD) tuner in it. For some reason that radio, even when the antenna is touching the transmitter antenna, does not pull it up. Is there any reason why this happens?

Whatsapp hasn't sent me confirmation code?

Whatsapp hasn't sent me the confirmation code. I've sent my email address to whatsapp's automated SMS number and it hasn't emailed me. It's been over two days. I also tried calling them at a different number where a machine is supposed to give me the code but the call won't go through. What can I do?

Ps I'm from Mexico and I'm trying to activate it on my iPhone 5

Will a case meant for iPhone 5 work with an iPod touch 5?

Specifically this one:

http://twelvesouth.com/products/bookbook_iphone5/

It is only 0.1 inches difference in height and.06 inches in depth. It might not be as smug, but it will still atleast fit right?

I plan on getting a ZAGG InvisibleShield full body coverage also, so that should increase the depth a little bit.

IMessage waiting for activation

For the past 5 hours I've been trying to get iMessage on my iphone 4s to start working again. It keeps saying it's waiting for activation and when I click send&receive my number is grey and won't check. Here's the catch, my mom just got an iphone as well and her number was under the same apple ID, so her number shows up as black with a check next to it as well as the email.

She has her own apple ID now, but that's not changing anything on my iPhone and neither of us can activate imessage for some reason. I've tried multiple times shutting off imessage, the network reset, and turning my phone on and off and nothing has helped. If anyone knows what to do, please help me As soon as possible. Going to the apple store is out of the question right now for reasons, so I really need an answer on how I can fix this alone.

How do I delete the second number off iMessage and stop my number from showing up as grey and uncheckable?
