I'm getting ready to root my Sprint Hero and install a different ROM. In all the research I've done I've seen several references to flashing or updating the radio? What is that? Are they talking about the firmware on a particular chip and apart from the main boot ROM? Or, are they talking about a device driver included with the ROM?
I would really appreciate it if someone in-the-know could explain this!
Also, how would you know if you need to perform this kind of update?
