RIM 857/957 the 2nd generation of BlackBerry

RIM’s next generation of BlackBerry devices looked a little more like the models we see today. The pager-style was ditched for a more PDA-style look. The display was increased more than twofold, going form 6 or 8 lines to 16 or 20. It also added the rechargeable lithium battery. However, RIM definitely found the model that would work in the future.
