I searched the whole web for a solution to my problem which just like this thread. I wanted to be able to cycle between landscape and portrait at the press of a button. Unfortunately I found no tutorials to do so, therefore I had to develop my own method and I wanna share it with the community.
*This doesn't require root permision! : )
This method isnt free

but afterwards you can rotate the screen by double tapping the home button.
1: Invest ($1.49) in an app by
Coin Soft[I] called "Orientation Control"
1.a After installing open the app to change some settings. Set the switch style to "Cycle". Then select Cycle Settings>Disabled Switch>Auto Rotate.
2: Now download a free app by
Hideki Kato called "Home2 Shortcut" and open after installing.
3: Now you need to set up "Home2". For step 1 of the Home2 set-up, select "choose Application>Installed Applications" and set it to "Orientation Switch"
4: Scroll down to step 3 of the Home2 set-up, and select "choose home application" and set it to whatever your preferred launcher is.
5: Finally read step 4 of the Home2 set-up, and do just as is says.
Now you can double tap the home button at anytime and rotate the screen. Hope someone finds this useful ; )
