Monthly paycheck of course. That was really a non-question...

PS: Stuff you are proposing should really be done in a different way. You do not present your super phone design to Nokia. You present it to little Chinese guys like the ones behind SmartQ, and you also follow up with some investment money. The amount will depend on how interested they are in your design (less interest = more of your investment needed). Then you try to manufacture your product with them and sell it. Manufacturing involves quite a few more steps than just the design and it costs money. If you are lucky (and it is a big "if") you may make some profit and end up being bought by a bigger company.
