That's because the images for the 2G were encrypted. No one cares enough about the device, since it isn't that advanced, and there aren't that many holes to be exploited. They care about the iPhone. Do you think if the iPod touch had been released first that it would have been hacked as quickly as the iPhone was (within a week, if I recall correctly)? Probably not. Jailbreaking began as a way of adding custom ringtones to the phone and progressed as people hacked apart iPhone OS more and more. The iPhone Dev Team was formed to find a free software unlock solution for the iPhone, and a jailbreak is an essential part of a software unlock. The iPod touch is simply an iPod; it can be easily purchased in many countries, free of a contract. The iPhone however, was only available in the US, and tied to one carrier. Even though the 3G is much more readily available than the original iPhone, it still isn't everywhere. However, because of jailbreaking, people are able to activate their phone in countries that aren't supported by Apple and are able to use hardware unlocks (even though they aren't recommended) and software unlocks. The 2G jailbreak may be very important in your eyes, but it isn't if you look at the whole picture. The iPhone is one of the hottest phones right now, and being able to use it anywhere is important. The iPod touch is also very popular, but there aren't any restrictions placed on it. Yes, having a jailbroken device is awesome, but not necessary in the case of the iPod touch. However, in the case of the iPhone, it is quite necessary.
