At the end, I had hoped, there would be some hardware specs included, like exact quantity/types of RAM/Cores/UARTs. And also, some more details about his next plans with the device. Maybe that'll be in the followup article ;)
I would be somewhat circumspect about publicly blogging about what I planned to do with a rooted femtocell. There's a bunch of laws that're pretty easy to break there, and a bunch of in house legal departments itching to fire off lawsuits at anyone encroaching on their expensive licensed frequency bands.
You get a potentially bidirectional serial interface. Whether there is a shell running or any input accepted is another question. Very often they are output only, merely for debugging.
You may get a tty with no getty/shell running, you may get a getty login prompt (which was probably this case, as the author proceeds to login as root with an empty password), you may get a custom CLI that only allows you to set some device parameters but no arbitrary command execution.

Not super familiar with hardware hacking. Does this essentially mean you plug in the write wires, run minicom, and get a terminal with a shell?
