iPad had been launched just a few hours ago and a little ago, Dev Team have jailbroken the new iPad 3G with the new tool, the Spirit Userland jailbreaking software for iPad. They have revealed some pics and a video in which jailbroken iPad 3G runs Cydia.
I will be posting more on this topic and also on how to jailbreak the device. So be sure to check it. Here is video showing jailbroken iPad 3G running Cydia.
