sir.. i found out that iPhone and iPad OS will automatically create rounded corners and add shadows to the icon.. from this site: http://www.axialis.com/tutorials/make-iphone-icons.html#t3    and  here:  http://www.axialis.com/tutorials/make-ipad-icons.html    .....sir, i just want to ask if  the icon that we will be submitting will be without shadows and in a plain square without rounded corners?

Your question is a design question.  We want the icon to adhere to the iphone format; if that means it should have rounded corners and shadows, then, please conform with that standard.  All the icons on my iPhone have rounded corners.   Hope that answers your question.
