Does any one know this kind of application is there for your mobile phone as well???

I want to make a tutorial about customizing Wisbar Advance Desktop themes and my sony camcorder is not giving the colours right and I have a lot of empty space as obviously it records in landscape and my tutorial will be in portrait.

So I want a program that starts recording my screen as I start my tutorial. Sound is not necassary, I can add the sound later on in Final Cut Pro.
Does something like this exist for mobile phones. I know it exists for desktops. Google " AVI screen Capture" give me a lot of results, but all for desktop

I need something without using a desktop... Just a program writing the info on your storage card. Sounds simple, but I really can't find it

Cheers,
Arnold
