Of course, since the firmware is open source, we would be very grateful for anyone who wants to explore it, develop forks or even alternate versions of it, contribute fixes, etc.: https://github.com/skysedge/rusp_firmware/

I'm very sorry about the condition of the software ... I had started a rewrite to get bare minimum functionality working (contacts, calls), but then my PhD program ate every bit of free time in my life....
