I recently jailbroke my iPhone 3GS and even with all the new additions that OS 3.0 brought us, in my opinion it is still worthwhile to jailbreak an iPhone. The main reason is for running apps in the background. The pure enjoyment of running Slacker Radio or Pandora in the background and then surfing online, texting, playing a game or using any other app is by far what I enjoy the most about using an app in the background. Especially when I'm running and using an online radio app and a running app such as Nike+ or RK Pro.
I havent noticed any negitive impact on my battery life when running a background app.
Besides the many other reasons to have a jailbroken iPhone, backgrounding is my favorite.

iPhone 3GS Background apps with Jailbreak
After jailbreaking your iPhone use Cydia to download a program called Backgrounder. Make sure its the one for OS 3.0. after installing that program all you have to do is run any app from your iphone/itouch and when its running just hold down the Home button and a alert will pop up saying "Backgrounding enabled" and then the program exits to the home screen, but the program is still running in the background. You can open back up the program and exit out as normal but it will always run in the background until until you hold down the Home button again while in the app that is in the background and an alert will pop up saying "Backgrounding disabled." All in all its pretty simple and you cant mess it up.
after you have downloaded the 3GS 3.0 firmware that you'll use on the jailbreak it takes 7-10 mins max.
here is the link to the 3.0 firmware.

For users of 3.1.2 - you can now jailbreak (and unlock!) your iPhone 3GS too as long as it has baseband version 05.11.07
Use Blacksn0w to unlock, jailbreak (and enable tethering). I'm looking forward to finally trying Backgrounder myself. Anyway, steps and tutorial are here: www.mobilecrunch.com/2009/11/03/tutorial-how-to-te...
