SoftBank borrowed all the money to buy Sprint from Japanese investors. As the $ appreciates in value vs the Yen, it gets cheaper to pay back the loans to those Japanese investors. So, who cares? Well it makes it easier for SoftBank to continue spending more money than they will take in from the Sprint deal as they continue to build up Sprint's infrastructure. It is also why Dish will never get Clearwire and Sprint will - cash to burn.
