Go to jailbreakevolution.com and download the program. Open it on your computer. Plug your phone in. Start process. This all takes about 10 minutes. It's safe, quick- it works.

There are seriously unlimited possibilities when it comes to what you can change, but here are a few examples and things I've done to mine so far...

I've added a brightness control to my home screen. I would get so annoyed every night when I would use my phone in bed and it was bright, and I had to go through several steps just to change it. So easy now!

I also made it so I can have 5 apps at the bottom of the screen instead of just 4.

I changed the "Verizon" at the top of the screen to "I<3porter" and also changed the Internet bars to stars (when it's on 3G it's a little tiny Volcom symbol).

I changed the theme of "notes" to a Volcom theme!

My home screen has been pimped out too. All of those little Volcom signs float around.

I made it so there's a background in the message app, and I changed the color of the text bubbles as well.

Also, if you've noticed, I've also reset the font. 
 
If you try this out, come back and let me know how you like it! Because I guarantee you will :)
