Misconception You cannot simultaneously measure both the position and the momentum of a particle.
Correct Physics This is the wrong phrasing of Heisenberg s Uncertainty Principle (HUP), which actually states that the position and momentum are not simultaneously determined. This has a very different meaning than what is stated above. Uncertainty is a property of the quantum state and not determined by how measurements are done. No matter how a measurement is taken one cannot change the inherent uncertainty determined by the quantum state of the system.

I'm sticking with that, as it matches what I've read in a multitude of books on the subject, including a book I'm currently reading: The Black Hole War: My Battle with Stephen Hawking to Make the World Safe for Quantum Mechanics by Leonard Susskind. In that book he gives an excellent description of the measurement problem.
But thanks anyway. I'm not trying to argue with you, just saying what I'm going with.
