[citation][nom]ericburnby[/nom]Direct quote from Google Analytics: "The Mobile Devices report lets you see visitor statistics by mobile device, brand, service provider, input selector (e.g., touchscreen, joystick, stylus), operating system, and other dimensions like screen resolution (all on the Explorer tab), and by the locations from which visits originate (the Map Overlay tab)." This is the free version. They have an Enterprise version with more functionality and even an SDK to allow you to use Google Analytics inside an App. Tell me how changing a user agent will change the data from an App that doesn't even use WebKit or doesn't browse websites? Or how a user agent change prevents GA from knowing your device make & model, the OS version or service provider?[/citation]
So, point me to a page that I can go to that Google will tell me what it knows about me. When you come right down to it, it's all just numbers flowing through a wire or beaming through the air. All Google knows is what numbers you send it. Maybe it can do some clever inferring or whatever, but all it has to go on is the information your device provided.
