Sony Ericsson has intentionally excluded the DuoPro driver from the P900 software. The P910i, except a few minor things, has the same hardware of the P900, and the same operating system and interface releases (Symbian 7, UIQ 2.1). Maybe some features can be isolated from the P910i software and transferred to the P900; I feel that SE won't do this (it's not a wise "commercial strategy" to enhance old models when new products are already in the shops). Anyways my "programming philosophy" is to use the P900 as a regular computer with graphical screen, "mouse" (touchscreen), some computing power, and a few megabytes of memory (plus some decent storage). This makes my P900 different than the P900 of other people. I am currently developing a Sinclair Zx Spectrum emulator for the P900, and it's a true programming artwork (getting 25 fps refresh in sync with Z80 emulation is not a joke; I had to unroll some loops "by hand" to get the most efficient assembler-code compilation). -- alf
