Want to second this - it's really nice from a security standpoint.

Yeah, whatever CPU that thing's packing may not actually be able to run standard Linux. It's probably running an RTOS similar to vxWorks or FreeRTOS.
If you really want to hack on this thing you'll have to find a JTAG header somewhere on the motherboard and/or try dumping a ROM image to see what it's actually running.
ETA: Looks like MMU-less configurations were added to the mainline Linux kernel a while back so it might be possible to compile a custom kernel for it if you can figure out what CPU it has - good luck getting the rest of the devices to work though.
Edit 2: Actually there's a decent chance it's running LiMo, but good luck hacking on that.
What kind of phone is it?
Grav has worked well for me
If you have a router then you're fine.
