The Samsung Rant was released not long ago (in October 2008, in fact), but it seems Samsung and Sprint are already working on a successor. The Samsung Exclaim (sometimes I think Samsung plays Mad Libs with its product names) is slated to be the successor to the Rant, and the big difference is that it has a dual-slider design; the number keypad slides down, while the QWERTY keyboard slides to the left. The design is similar to that of the Pantech Matrix and the Helio Ocean 2.
It has a 2.6 inch QVGA display, EV-DO Rev. 0, support for various social-networking applications, GPS, a 2.0-megapixel camera, and a microSD card slot that can hold up to 32GB cards. It'll be available on June 7, but price is yet to be announced price. You'll be able to get it in either blue or pink.
