just wondering if anyone knows first off, if 4GB pro duos are supported on the w810i? On the website, it keeps saying to upgrade to 1GB, but then I also saw mention of "upgradable to 4GB." I can't find anything in the book, so I just want to confirm with someone who knows for sure. I figure I'll get a 4GB and if it doesn't work, my PSP can take that one and I'll take my 1GB from my PSP instead. Also, does anyone know if getting a so called "high speed" MS will make any difference in photo/video quality or anything like that? I know I've heard conflicting reports about compatibility with other devices, but does anyone know about this phone specifically? Thanks.
