Dear Linux experts,

We are in the process of making a mobile handset (like cellular phone)
based on RISC Processor and Linux based OS. I am looking for which
linux OS is best and cheaper, mainly our budget is very low, so
looking for cheaper one.

How about RH?. We are thinking we are not going to use all the
functioanlities, we will use someof them only. Our Flash size is much
smaller. Also does anybody have any idea do we have to pay amy
royalties and licensing once we start selling mobile handsets.

I am new to the business, can somebody suggest me those details
(licensing and royalties).

Thanks in advance and appreciated.
