  We show that all finite dimensional pointed Hopf algebras with the same
diagram in the classification scheme of Andruskiewitsch and Schneider are
cocycle deformations of each other. This is done by giving first a suitable
characterization of such Hopf algebras, which allows for the application of
results by Masuoka about Morita-Takeuchi equivalence and by Schauenburg about
Hopf Galois extensions. We also outline a method to describe the deforming
cocycles involved using the exponential map and its q-analogue.
