Iowa Code § 902.4
For a period of one year from the date when a person convicted of a felony, other than a class "A" or class "B" felony, begins to serve a sentence of confinement, the court, on its own motion or on the recommendation of the director of the Iowa department of corrections, may order the person to be returned to the court, at which time the court may review its previous action and reaffirm it or substitute for it any sentence permitted by law. Copies of the order to return the person to the court shall be provided to the attorney for the state, the defendant's attorney, and the defendant. Upon a request of the attorney for the state, the defendant's attorney, or the defendant if the defendant has no attorney, the court may, but is not required to, conduct a hearing on the issue of reconsideration of sentence. The court shall not disclose its decision to reconsider or not to reconsider the sentence of confinement until the date reconsideration is ordered or the date the one-year period expires, whichever occurs first. The district court retains jurisdiction for the limited purposes of conducting such review and entering an appropriate order notwithstanding the timely filing of a notice of appeal. The court's final order in the proceeding shall be delivered to the defendant personally or by regular mail. The court's decision to take the action or not to take the action is not subject to appeal. However, for the purposes of appeal, a judgment of conviction of a felony is a final judgment when pronounced.
