The 818 fb-1 dataset collected at the psi(3770) resonance in the CLEO-c detector offers unique possibilities for measuring strong phase differences in neutral D decays. The measurements require that both D mesons in the event are fully reconstructed, usually with one decaying to the signal mode of interest, and the other to a CP eigenstate. The strong phase differences extracted from these decays are important inputs to measurements of D-mixing parameters and the determination of the CKM angle gamma in B --> DK decays. Results will be present from a variety of D decays including KSpipi, KSKK and other 3- and 4-body modes. The impact of these results on the measurement of the CKM angle gamma/phi3 will be discussed.
