What's a good car mount that let's me keep on the case and doesn't stick to the windshield? Couldn't find anything that matched my requirements on amazon.
One mount by Kensington holds the iPhone by gripping its sides, which lets you have a case on it. Also, it has both a suction cup and gripping clamps, for diverse places to hold. For example, you'd be able to grip it to a ventilation grid if you were to use the gripping clamps.
I'm hoping the Magellan dashboard mount that I have from a previous iPhone works with the 4S. For GPS it has an enhanced GPS and speaker. Supposedly it does.
