Google Ad Phone?

It seems that Google is in the process of teaming up with wireless phone manufactures to make a Google phone. Is ad supported Cell Phone service going to work? Well myself if I could get free cell phone service by just having to hear a brief commercial or reading a text message ad I am all for it.
The problems I see is Google being able to convince the major carriers that they can make enough money to keep them happy. Or as we found out just last month Sprint and Google are teaming up to offer wifi service or something similar. Maybe the plan is to offer the official Google phone, ad supported wifi and cell phone service for free.

I am all for it, viva la Google phone.
