Why I Jailbroke My iPhone 3G

I've been an iPhone owner for about a year now, and I have jailbroken it off and on throughout the time that I've owned it. When I first got the device I jailbroke it to play with some of the apps people were developing, but I really didn't see any that were must-haves, and they especially didn't touch the quality of what's available in the official App Store today.
