Why can my iphone only play music with just the right bud/speaker on headphones?

I've had the Iphone 4 for a bit now and recently i noticed that the left bud on one of my headphones don't work. I thought it was my headphones so i went out and bought a new pair. Only the right one works in those as well. I tried others too and then when the another person tries the same headphones on their ipod both work. What exactly is the problem and how can i fix it?

Buzzing sound studio monitor?

I had the m-audio bx5a deluxe, the left speaker's tweeter burned out, smoke came out of it. Maybe its just bad luck.left one works fine.

i just got a a pair of yamaha hs80m and when i plunged it in, it has a buzzing sound.
i tested it on my iphone and laptop and it works fine, no buzzing sound.

went out and got the monster power center (power conditioner), plugged the computer power cord into the monster power center and its still doing the same thing.
i'm using the soundblaster x-fi (sound card), corsair hx1000w (power supply),
no on board audio so i can't test and see if my soundcard is causing the problem, but why my yamaha buzzes but the m-audio doesn't buzz

anyone has or had this issue please advice because i hate to go out and get a new sound card and find out that the powersupply is bad (not properly ground or something)

so is the problem caused by the power supply, or soundcard

i've tested multiple devices so i know its not the cable or the speakers
i unplug the wires that goes into the pc and the buzzing sound stopped so i know something is wrong with the pc but i'm curious why the m-audios don't buzz like the yamahas

Apps on my iPhone 4S keep crashing?

Today I just downloaded 2 new apps on my iPhone (both for maps and GPS) but shortly after I did, I noticed everything I do on my iPhone is delayed, and keeps crashing and isn't working properly. I just got this phone like 4 weeks ago. It's brand new, and I don't have much on it. I deleted both my new apps to see if that would make it better, but it didn't.
I don't get it. Is there a bug on it now or something?

Will verizon give me a new iphone if mine cracked?

So, my dad bought me an iPhone 4s a couple weeks ago and we both swear the guy activating my phone said that if something happened to it that they couldn't repair there, they would give me a new phone if I had warranty in exchange for my other one.
I had come home from school and noticed that the back of my iPhone was cracked virtually all over. I had not dropped it or anything, so it might have happened at school or something, but that's not the point. I just want to know what I would have to go through to get it fixed with little to no cost at all right then and there.

How to connect my iPhone4s to a new laptop?

I have an iPhone 4s and I use my desktop pc (Win 7 64 bit) to update the music on it through iTunes, It is set to manually manage music and when I add a new cd or downloaded album to the iPhone I delete it off the PC to save space (I have a lot of music, it's a practical solution), problem is when I plug the iPhone into my new laptop it's set to automatic sync, despite me changing this in preferences, I go to manually manage music in the iPhone main menu on iTunes and then click apply, but it tells me if I do it it'll wipe the iPhone and from doing this once before when I bought the desktop PC I don't want this to happen again as I don't have backups. Is there a way of extracting the music off the iPhone so it's not an issue if I wipe (I remember the old iPods you could go through the hidden folders and take the files) or alternatively change the laptop to manual without wiping the iPhone?

Is my iPhone battery permanently ruined?

I have an iPhone 4, and I know what I did wasn't the smartest, but I'm hoping my battery hasn't been ruined. So I took my phone off the charger at 99% because I had to go somewhere and couldn't wait any longer. I worried that doing that would hurt my battery, so when I got home, my battery was at 97%, and I thought I would put it back on the charger to finish completely which I hadn't allowed it to do before. Now, my battery percentage is going down easily every minute when before, 100% would last me about five minutes, on Facebook and listening to music. What to do? Is my battery all done and will never fill up again?
