"Aren't phones supposed to be using Nand?"
AFAIK only Samsung has a phone on the market that uses NAND flash. And that is only one out of their whole line. Beyond that, there was that Toshiba exec. who said there were companies in China who are making phones with NAND flash, but it is difficult to quantify this. Maybe they are for Asia only, but I haven't seen any signs of them. Rumor has it that Nokia has a NAND flash phone in the works, but I don't think it has been released yet, or even if it ever will be.
Regardless, NAND flash is far away from being the dominate flash in phones. Whether or not it will be is a topic that can be argued either way, it isn't a clear winner.
