As mentioned before, the Samsung Instinct S30 is the followup to Sprint’s most popular phone from last year. Originally, the Instinct was positioned as an iPhone killer. While that never actually happened, the Instinct was a great phone in its own right; easy to use, reliable, and offering a good user experience. I mean, I use one. Sprint and Samsung released the S30 to follow up on the goodness that the first Instinct brought them. While there are only a few differences between the previous generation and the S30, the new model fills a crucial role for Sprint, especially with the imminent release of the Palm Pre.
