The WSJ has an article titled, "AT&T, Verizon Still Pouring Billions Into Mobile Networks". It notes that cellcos have already spent billions upgrading their networks to 2.5G and 3G -- and now will spend billions more on 4G.

In addition, both companies are also dumping billions into International routes, domestic broadband networks, and their respective triple play networks, U-Verse and FiOS. 

On top of that, both companies have been acquiring companies, like Alltel and Centennial. Ummm, how are they not toppled over in debt? 

These companies have felt intense pricing pressure from cable companies as well as T-Mobile and Sprint. Customer Acquisition and Retention costs have to be high, even as ARPU remains about the same. Debt costs more right now. Wireline income has been declining for at least 4 years.

Where's the money coming from?
