Problem with iPhone 4 sending texts?

I've been trying to text my boyfriend and the past two days the sending bar gets about 9/10 the way sent then just stops and says message failure or something like that. It's only with his phone though. I can send texts to anyone else. Any ideas? I have tried turning off my phone then back on it didn't work though. Any tips are greatly appreciated.

2004 Volkswagen GTI VR6 Battery problems?

I bought this car on Saturday with 105, 000 miles and it has an aftermarket Pioneer head unit that you can play music through iphone or ipod. The first day I got it, I sat in it without turning the car on just so the battery turned on and I played some music through my iphone. I did this for about 10 minutes and I was fiddling around with the bass setup and reverse speaker and or normal speaker, and the hertz from 50 hertz to 125 hertz. The next day I did the same thing and when you turn the car off you have the option of taking off the head unit (It slides right off) So I figured sure Ill take it off and put it in the glovebox, So I did that and locked the glovebox. Next day I go to get plates to register the car, and the car wouldnt start, my dad immediately told me that I shouldnt have sit in the car and played music. So we charge up the car with a battery charger, the black terminal (negative) had a bunch of dirty stuff (I'm guessing corrosion) around it so we cleaned it up with some terminal battery cleaning tool. Then it started up fine. So we took it for a ride and I plugged on the radio when the car was off, then I noticed shortly after it said Change alternator error on the dash and it was dimmed. So I pulled over switch seats with my dad and he drove it back home, on the way home the setup on my head unit was going crazy switching bass from -6 to +6 without anybody touching it, So I slid it right off and put it in the glove compartment. Came back home charged it, and then took it for another ride without the radio. Please help me, Do I need a new battery or a new alternator, or maybe should I get it checked out first by a trusted mechanic?

I'm So LAZY ITS NOT EVEN FUNNY?

So honestly I'm one of the MOST LAZIEST PEOPLE EVER. I don't do anything but go on the internet and my iphone and twitter and just UGH. I'm so lazy and unhealthy that sometimes I sit all day in my pjs watching tv and just eating and going on the internet. How can I be active and start exercising more and be motivated?

IPhone plugged in but battery is going down?

My iPhone 4 was at 20% so I plugged it in. I checked on it and it was down to 3%. Now it's totally dead. It charges to 5% (enough to turn on) then just drains back to 0. The cycle won't end. Anyone know what's wrong or what I can do? I already cleaned it and tried different cables and outlets.

Will Skype cost if i do this?

I already looked into it but i just want some reassurance. All i'm going to do is use video with one person at a time, i'm not going to be calling any phones, just video chats with one person, but one of the persons is from a different country then me, so will it cost to video chat with them? I'm not going to be using a laptop either, i have an iPhone so i'm going to make an account through the app and just video chat using the app, so no costs right?

My iPhone 4S does not charge or connect to my Macbook Pro

When I plug my iPhone into my mac nothing happens, it does not do anything. It doesn't charge or connect to iTunes. I've tried rebooting my iPhone and mac several times and neither have worked. I've followed the steps on Apple and many other sites in order to reset my USB ports, reinstall iTunes, etc. In order to fix the problem and nothing has worked. I don't know what the source of the problem is either. I have two cords, both in normal shape, that don't work. My iPhone charges when I plug them into a wall outlet hub, so the problem isn't the cords. The last time I connected my phone to iTunes was probably a couple months ago, give or take. I feel like I've tried absolutely everything. Is it my phone, my mac? I'm trying to avoid going to Apple or Verizon in order to find the fix as it will most likely cost me money that I don't have (My screen has cracks, etc.) ANY help at all would be appreciated. I just want new music on my phone. :'
