Nokia has started deliveries of its E61 business phone with full keyboard, a model <A HREF="http://www.eweek.com/article2/0,1895,1956890,00.asp?kc=ewnws050306dtx1k0000599">directly competing with RIM's BlackBerry</A> device. The E70 model, with a 2 megapixel camera, is expected to start shipping later in May. The first E-series phone, the E60, went on sale in April. The three E-series phones, aimed at business users, and three of Nokia's flagship multimedia N-series handsets missed their original target shipping dates due to software- related problems.
