Just how does AT&T plan to pay for the swarth of spectrum (public airwaves, anyone?) it won yesterday? Creatively! Reuters reports that everyone’s favorite iPhone provider will use a “combination of funds from operations and debt” to pay the bill, which totals around $6.64 billion. It’s got 10 days to pay the down payment of $1.33 billion, and then 20 days to pay the remainder.

So, bottom line, AT&T has 10 days to pony up more than $1 billion. Easy peasy.
