How to watch videos on my iPhone 4S?

I'm trying to watch a video on my browser (not from YouTube) but all I get is audio and no video. The only thing showing up on mu screen says "TV connected. Connected to TV". Tried different browser, chrome vs safari, same thing happens. Tried different non YouTube videos as well.

Does data storage matter for iPhone?

I've never had a phone before, so I'm really new at this. I'm looking at Apple's website, and I click on something that lets me see plans from Verizon, At&t, and Sprint. They all charge money for data. My question is, does that matter? Should I go for the cheapest plan or what? The iPhone has gigabytes for data and storage and stuff, so why are the phone companies charging money for data? I'm so confused. I would appreciate any help.

My iPhone is on charge and keep going off charge then back on again. Why?

I have my iPhone plugged into the charger that is plugged into the socket in the wall. I've never had any problems before.

It is plugged in and it says it's charging at the top and then it will vibrate and say it is not charging and it will go back on charge again. It has been doing this all morning.

I have checked to make sure the switch is on and that everything is in properly and that is all fine. It seems to be alright when it is plugged into my laptop using an extra USB lead.

It is quite annoying so I would like to know if there's anything I can do even if it is to buy a new charger.

Update Fail on iPhone and Now It Won't Get Detected By Computer?

Background Info: I have an iPhone 3GS that I wanted to update to the latest iOS software (6.0 I think) and after the update had been downloaded, and while it was being applied to the phone it crashed and the update was unable to finish.

Now, my phone is stuck on the screen which shows a USB connector with an arrow pointing to the iTunes logo, asking that I connect it to iTunes. When I do, the computer doesn't detect it's been connected, so I can't do anything.

I've tried the solutions on various forums, the Apple Support pages and I will contact Apple if nothing works. I've tried to restore it by holding the off and home button down, I've tried different USB ports on my computer, I've tried holding the home button as I connect it and nothing is working.

If any of you share this experience, please let me know of your solutions, Thanks.
