In the Catholic Medieval theology (so that's the first 1500 years) the Jewish prophets were in Hell, though possibly without torment, until Jesus freed them when he himself entered Hell.
The Protestant response - method of saving aside - would need to be the same. Nobody gets into heaven (dead) until after Christ's Death.
Now - the "possibly still is" comes from the fact that certain Christian sects interpret entry into heaven as only coming after the Apocalypse -in which case everyone who dies is currently in some kind of Limbo, in Hell, because there's nowhere else to go.
