How to transfer a playlist from iPhone to iTunes?

I made a playlist on my iPhone and it REFUSES to download onto my iTunes. The playlist has not been previously downloaded to my computer so the "export" "import playlist" method is not working. I also backed up my phone to icloud. All of my music and purchases have been downloaded. The playlists are the only thing I can't figure out. Can somebody help me?

Has the iphone ruined my computer?

So i had a friend over, and he wanted to use my computer to transfer all his pictures on his iphone to his flash drive. I usually don't let people hook their iphones to my computer because itunes always pops up and kind of slows my computer down. But i went ahead and let him do it. Now, i didn't monitor his actions but as far as i know he just transferred the items onto his flash drive, but during the time his phone was hooked up, my computer fan started getting loud and my cpu usage spiked at 99/100% so i told him to disconnect his phone. Now it won't stop. I turned it off over night and right now is my first time being back on it. The usage spiked before i even opened anything and the fan is still loud. Does his iphone have anything to do with this? And more importantly, how do i get it to stop? I've had this computer for years and i know i need to get a new one soon probably but i don't have the funds right now.

How to clean iphone speakers?

Hello Everyone: This is my first question!
After a very interesting (drunken) night, I woke up to find my iPhone 4S in a bowl of spaghetti sauce. The phone seems to be working fine, but the speakers are clogged with congealed meat sauce. How can I clean the speakers?
Also, I dropped my phone in the toilet a couple months ago, after which something happened where whenever I would try to play a song, the volume would automatically drop to zero. However, the volume would turn back on when I clicked Siri. The problem has now subsided a bit, but it happens again every so often. Can this be fixed?

PS I can't send my phone back to apple because I already had it replaced when I dropped my phone face down in Target and the screen became unresponsive.

Can I flash an iPhone myself?

I have a brand new iPhone 4 from Verizon that I want to flash to Cricket services.

All the good cellular stores around my house are closed cause it's Easter. I mean, waiting a few days isn't gonna kill me, but I need it just as soon as possible as my other one is not working right.

Is there anyway I can do it myself? Step by step directions/process?
