Sprint has few options at this point. While it's true that the entity won't go away, the reasons to stay with them (unlimited data, ridiculously cheap legacy plans, persecution-free tethering) will. If the new owners understand consumer technology and have deep enough pockets to both turn it around and acquire new spectrum (Apple, Google) it might be a good thing.
Unfortunately, I think a few well-placed campaign contributions and drug-fuelled visions will result in a series of owners who buy it, try a clueless approach to turn it around, fail miserably then sell to an even more evil and clueless entity who will repeat the cycle. Sprint's going to get passed around like a drunk freshman co-ed at a fraternity party.
I'm already mapping out an escape plan. Surprisingly, there are a lot of MVNOs around with decent pricing.
