Yes, that's right, Krusell's Windshield Holder is designed to conveniently mount mobile phones, GPS and PDAs to car windshields (or windows, if you prefer).
It's all in their Multidapt technology, a series of clip or swivel "solutions" for mobile phones, etc.
(And don't forget to keep it hands free when you're behind the wheel.)
