iPadian is created by Adobe AIR, and is a third-party software so it can in no way have the real safari browser, the browser shown here is not safari, but a simulation of it. But shouldn't these prompts appear in a browser running on iPad?
There is one of two things happening:
Either the browser agent is set to that of the browser agent of an iPad iOS device which means Google would make the suggestion themselves.
The other possibility is that the simulator itself is adding that frame to the page since that’s what would happen on I real iOS device.
