Root: Samsung Galaxy Tab 8.9 GT-P7300

Just bought a new Samsung Galaxy Tab 8.9 P7300. Well, there's a lot of cool things we can do besides of playing games, social networks, notes, or whatever entertainment. For some of you probably software developer might want more 'fun' with it. But with factory settings nothing much we can do even you can't run a software as simple as phone call apps or access to a little special command on terminal console. So, before we start read the following:

Warning: Please make sure you have a backup copy of your firmware.
