Where did Jesus go and what did he do between His death and resurrection? (non-Trinitarian perspective)

How do non-Trinitarian Christians respond to the question *where did Jesus go and what did he do between His death and resurrection?* *** *** This question is asked as a parallel to this existing question . Since the scoping of the earlier question was tightened to specifically solicit the input of Catholic, Orthodox, Anglican, and other Protestants, and a variety of users had offered answers from other viewpoints, this question is being asked to provide a place to respond from these other viewpoints. Scoping for this question would certainly include The Church of Jesus Christ of Latter-day Saints, Jehovah's Witnesses, Biblical Unitarians, and the Swedenborgian Church. However, if between this question and its predecessor there is a Christian viewpoint that is still excluded, I would be happy to edit the scoping of this question so that between the two questions a more complete set of Christian denominations can be represented.
