That argument would hold water if it wasn't Sprint, which has seen customers literally running to competitors like ATT and Verizon in recent years. And I'm not sure the company is even profitible.

I predict they'll lose even more customer base, once the 3G iPhone is released. Sprint will react like usual, by bombarding your phone at night with offers for free cheap phones if you sign a contract with them.

And we all know how well that worked after iPhone 1.0...
