The Motorola A780 is a Linux based cellphone (something I all ways wanted to have). I just found a nice article on Symlink.ch which has some very interesting details about the device. I especially like the telnet server without root password and the SAMBA server which shares / (root directory).
Will this be the next big thing for Linux hackers?
I guess the phone is as secure as any other embedded Linux device, where everything runs as root.
