Update,Jailbreak & ssh to iPod Touch 2G


Today one of my office friend bought Ipod Touch 2G 8 GB it was quite good but it was using old firmware version ,as the latest 4.0 has been released so finally planned to update the latest version. Using the latest Itunes application i was able to updated to OS 4.0 which took 20 minutes to update.
Now new firmware looks very nice but i cant mess with most of things like installing custom tools by using the http://www.ihackintosh.com/2010/06/how-to-jailbreak-your-ipod-touch-2g-using-redsn0w/ guide i was able to jail break and have access to Cydia it is a replacement packaging and repository manager for the original Installer.app for the iPhone or iPod touch, once i followed the above guide i was able to jail break the ipod touch with the latest firmware and had access to the Cydia.My next plan is to use Cydia packages to install ssh on the ipod touch so that i can ssh to the device,install and configure the applications. Finally i was able to ssh to IPod touch from My Ubuntu desktop see the below Screenshot.The main objective of the above task was to use Ipod touch has an mobile penetration testing device ,next i will try to post on how to install tools like metasploit,nmap and other security tools.
