I just purchased an ipod touch 2g after losing an average mp3 player. I'm in the process of learning "tricks" I didn't know applied to the device. For instance, my son showed me how to "pinch" the screen to increase/decrease the web pages. So I knew there HAD to be more tricks out there. In the process, I found the term "jailbreaking". I've been trying to figure out what it means. What benefit would I have by "jailbreaking"? The only advantage I've seen was to change the image on the startup screen. If this is it, it doesn't seem worth the risk. Any input is appreciated.
