The Reciva Radio uses GPL code, and fortunately for us, this gives us the right to obtain, build and install our version of the code.
"Some devices are designed to deny users access to install or run modified versions of the software inside them, although the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users' freedom to change the software. The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such problems arise substantially in other domains, we stand ready to extend this provision to those domains in future versions of the GPL, as needed to protect the freedom of users." - GNU GPL Licence Aggreement
The intention is for our code to build on the Reciva GPL base, with additional applications (again, based on open source applications), and produce an alternative radio application for the Reciva hardware.
