Is this device more important than the iPhone?

We already knew that AT&T (NYS: T) was going big with the new Nokia (NYS: NOK) Lumia 900 -- bigger than even with Apple's (NAS: APPL) iPhone.

Ma Bell's device chief, Jeff Bradley, recently told CNET that the device's launch would be "a notch above anything we've ever done," iPhone included. Thanks to a recent report from Ad Age, we have an idea on how many marketing dollars qualifies as the biggest launch ever -- $150 million. That amount is more marketing muster than AT&T threw behind the iPhone when it enjoyed nearly four years of exclusivity.
