Not likely at this point. T-Mo will probably wait a while, let Sprint sink even farther or go bankrupt, then buy up what it needs at bankruptcy prices. See Chrysler/Fiat.

They would converge at the changeover to LTE. That way they only have to give Sprint customers new phones once instead of twice.

If Palm is still around by then. They, like Sprint, are still bleeding cash like a stuck pig...

Rumor has it that Nextel may be sold off as a separate company specializing in emergency communications. Sprint would retain most of Nextel's bandwith, (that bandwidth is what Sprint really wanted Nextel for in the first place anyway) whatever they don't need for emergency services.

Bottom line is Sprint needs to be rescued by T-Mo much more than T-Mo needs Sprint's headaches. Sprint is a complete mess. But I can certainly understand T-Mo wanting to pick up 30 million+ customers and a lotta bandwidth if the price is right.

EDIT: Texaslabrat beat me to it with some points while I was typing. But we clearly agree about convergence with LTE and a large part (most?) of Sprint's value being the bandwidth they control. And obviously, if there's a merger and LTE rollout WiMax is redundant and toast.
