Thanks to just-completed work by Sprint, you can now yak on your cellphone in BART stations from 16th St. south. However, no service is guaranteed in the tunnels between the stations.

You can already use your cellphone in the Market St. tunnel, I’ve found. Transbay service is said to be next on the list.
