Samsung Instinct Mini?

There are rumors that Sprint and Samsung are busy working to come up with a smaller, cheaper version of the popular Samsung Instinct phone. While it’s not entirely clear whether such news is actually being spurred by the recent rumors of an Apple iPhone nano, but it could certainly be a competitor to the iPhone nano if it were to be released. How low would Sprint and Samsung sell this phone? If they are willing to offer it for free on contract, that would seem rather attractive, wouldn’t it?
