Iphone 5 Music Troubles: Ipod skips over certain songs?

I download all my music from an app but that has nothing to do with it.
It didn't start doing this until just today. I've used that app to download over 300 songs, suddenly when I press shuffle for jogging, it skips right over songs. It shows the album and everything but skips before it starts. I restarted my phone, re-synced, and even backed it up and restored it, it keeps happening. Now i've checked on my computer itunes library and they all play fine but not on my phone? Should I redownload the songs? Anyone else going through this?

Definition of application pending?

Not quite sure what this means so if anyone could tell me that would be great.

My iPhone broke. Should I take it to the apple store or AT&T?

The microphone and speaker on my iphone don't work anymore. I don't think there's any type of water damage, and i really don't know how it happened. I'm still within my 1 year apple warranty, but the nearest apple store is pretty far away. I was wondering if I should take it to att or the apple store. Will they do the same thing to fix my problem. Oh, and I'm paying att for insurance.

IPhone 4s with Virgin Mobile?

I need a new phone and I was looking at the iPhone 4s. Virgin Mobile is my carrier and I understand that they now have iPhones. But, I don't want to pay $400-500 for a phone, even if it's not a contract thing.

My question exactly is if I buy an iPhone 4s off craigslist or Amazon, where it's way cheaper, and I unlock it myself, is there any way to make it work with Virgin Mobile?

I looked and found out that VM uses CDMA, but most iPhones are GSM or something else. Is this a problem as well?

Thank you.

Added (1). Please explain why other iPhones won't work, please.
