On the software side of things the closest you can get is a phone running OsmocomBB. That only runs on some dumphones and is not useful from a user perspective, it is only for research. For smartphone software, the closest you can get is a phone running Replicant. That still has all the embedded proprietary software; baseband OS, bootloader, wifi/bluetooth/camera firmware etc.
On the hardware side of things, we have no ASICs with libre designs. I think there have been some cases with libre designs but none manufactured in large quantities. There are myriad patents covering various hardware processes, instruction sets, CPU stuff etc. See bunnie's talk about layers of openness and the Novena laptop for more on this.
RMS uses other people's phones, he doesn't have one himself, mainly due to the network side of things though.
Wow, I guess that there aren't really any "fully open" phones in that case.
For the truly paranoid (with or without reason), I guess that they would have to go the RMS route -- or find a payphone that isn't within sight of a security camera.
