Dish Network CEO Joseph Clayton told Bloomberg today that he'd try to partner with T-Mobile if AT&T's bid to buy the fourth-place carrier ultimately fails at the hands of a skeptical FCC and dismissive DOJ. Dish started buying up spectrum earlier this year for a planned LTE network, and Clayton says he could use T-Mobile's spectrum to build a real competitor to AT&T and Verizon — and if T-Mobile's not interested, he's also willing to go to Sprint. It's not the first time Clayton's riffed about a partnership with a wireless carrier, but with the AT&T / T-Mobile deal looking virtually dead on the wire, it's the first time he might be able to do something about it.
