around the middle of the video it shows how to convert to p12.If u fallow this tutorial made by Lee Brimelow u should be ok.

Relaxtraja are you on a Mac or have access to one, if so this is about 100% easier. Let me know and Ill find a tutorial for you, its simple once you get used to it. Even if you plan to develop on PC you can do this p12 part on a Mac and then switch to PC for the rest of the app until its time to release it, that requires access to Application Loader.

Lee made a video on the process here

I forget, but I think it was the video titled:

Developing iOS Applications on Windows

EDIT:

or perhaps its this one

Building iPhone Applications with Flash

You need OpenSSL and a fondness for typing on the command line. The process is explained on two pages, starting at "Generate a certificate signing request on Windows":
