Knowing how to do it is one requirement

If you are asking here in the way you are asking, you need to head to school for a few years, especially since "circuit" is such a generic term, it can mean pretty much anything inside a phone. I have friends that went to school for 6 years to be able to work on a small part of a CPU design to give you an idea of the time it takes.
