I have an iPhone 4S on the media cradle which I just updated to iOS 6.01. I see no difference between 6.0 and 6.01 in terms of functionality. All the message menus are still there, I still apparently get text messages, and emails if I turn off alerts and turn back on again.
My other phone is a Galaxy Nexus operating with Android Jelly Bean, 4.1, I get no messages at all...FWIW. I thought 4.1 incorporated MAP protocol.
