Yup. Some tech blogs have already covered this. The Instinct will be released on June 20th, and most of the advantages in features that Instinct has over the iPhone will most likely be void with the new version of the iPhone.
This is Sprint trying to draw in more customers with a new product, much like AT&T with the iPhone; however, AT&T and Apple did not do direct comparisons and competitions, which I think is a flaw by Sprint.
But you can't deny one thing, that the current iPhone does get beat in those tests, but the new iPhone is around the corner!
