There was a screenshot leaked months ago in which iPod Touch was running Windows 7 but that was true. Cydia is filled with a new application/tweak named iWindows. There are many random tweaks which allow you to run mobile OS in iOS with one touch but this tweak, with one touch will run Windows 7. Its a simulator in short. It weighs 2.1MB and is available for free form the BigBoss Repository.
This tweak for the folk’s who are addicted to MAC can be amazing to have a touch experience of Windows. Till now there are only two features which can be used and they are he browser (Google Chrome) and Text Editor (Notepad).
