How to add subtitles or words to a video clip on my computer?

I have a video (taken by my husband's iPhone) of a song that a group of us sang for friends at their going away party. I'm copying the video from my computer onto a DVD-RW, but I really want to add the lyrics of the song onto the video, like subtitles or like a Karaoke song. I know how to photoshop images really well, but have no clue how to edit video.

I have a Macbook Pro laptop, (If that matters.) Can I do this with "Garage Band" (a program I already have but have never used)? Is there an iPhone app or program I can use to do this?

Any help would be appreciated! Thank you!

Added (1). My version is "Mac OS X 10.6.8"
The video file format? It's a.MOV
Is that what you meant?

Is it possible for me to UNLOCK my Sprint Iphone 4s?

I really need to switch carriers because I can't afford Sprints prices anymore!
Is there anyway I can unlock/jailbreak a Sprint Iphone 4s. To the best of my knowledge
I don't think there's a SIM or anything. But with all the hackers out there someone has to
know how I can make my SPRINT IPHONE 4S compatible on other (cheaper) networks. Or am I better off buying a different iphone that uses SIM and doing this? I love the iphone but I'm a broke college student. I don't want to pay more than $60 a month!

How to reinstall cydia on a already jailbroken iPhone 4?

Ok I've just about given up on trying to install cydia again
Here's how it disappeared: I was removing some package that I had on there and then it disappeared
Method's I've tried to fix it with:

1.iFunbox and other things like that using the Cydia AutoInstall method

2. I've tried installing mobile terminal using that aswell but it didn't work

3. I can't use the iFile method because I don't have it installed the only app that's left is Winterboard for some reason

4. I've tried doing a restore through Itunes but all sorts of different errors pop up

5. I've tried using the Redsnow jailbreak to reinstall cydia but it come up with an error " Please reboot your iPhone with a clean slide to turn off swipe" or something like that

6. I've tried jailbreakme.com

7. I've tried restoring it with the Redsnow option

8. I've tried using Tinyumbrella

And multiple other methods

Cydia is gone but Winterboard is still there I had a few other cydia apps installed but they all disappeared or they were just tweaks

If anyone has a solution it would be much appreciated thanks

I just bought my iPhone and my sister and I are only sharing 2 gigs. We have verizon share everything plan. I know some apps use the Internet but will playing my games use my data even if the don't use the Internet. Like boggle or Tetris things like that. I know I can play those games on my itouch without Internet access. Also just other things that will eat it up. I have turned off cellular data until I actually need to use it so it doesn't use up my data. Just a list of things that use cellular data on my phone would be nice.
