Tokyo - Japanese wireless developer NTT DoCoMo on Tuesday introduced several new mobile phones, including one with a touch-sensitive screen and another that features aromatherapy skins. The D800iDS clamshell handset, from Mitsubishi Electric, features a touch-screen that will let users send handwritten messages and drawings, and likely figure in some gaming applications. Sony Ericsson's SO703i "aroma" handset will be available in nine different designs, each with its own uniquely scented skin designed to relax users while making calls.
