To jailbreak your iPhone 4 - just open up your mobile Safari on your iPhone and go to http://www.jailbreakme.com and then "slide to unlock." If the screen doesn't show up anything other than the background, then reload it again until it says that it is downloading. It took me 3 tries on 3G before it worked.
After that it should say "Sit tight" and this is the part where it is jailbreaking and preparing to install Cydia to your iPhone 4. Once everything is done, you should be good to go!
UPDATE: It appears that after the JB process if you reboot your iPhone 4, FaceTime and MMS will vanish completely. To fix that please use this guide from Redmond Pie: http://bit.ly/djyMpG
After following those easy steps, my iPhone now has FaceTime and MMS again!
Some people asked me where I got the "grid background" wallpaper. You can find it here: http://bit.ly/9Gu1td
