So, I went and bought the just mobile holder that mentioned above.
I highly recommend this. It has a very small form factor and is really firm in holding the phone. It has several options within the dashboard way of mounting.
Highly recommended.
My biggest problem is the landscape mode problem. I can get the maps app or the google navigation app to be in landscape mode but if I go to dialer it's funny to see and interact in fallen portrait mode. Even the settings shows in portrait even when the phone is landscape oriented. So much for IOS 6.
Anybody has solutions ? It's such a simple obvious thing, how could the Cupertino guys miss this ?
