When I booted the N770 from internal flash memory, I couldn't run as many apps as I booted from MMC card, so I thought the MMC card had already done the job extending the real memory. But, seems I was wrong. Now my N770 is booted from MMC card ext2 partition(around 450MB). From command "top", I can see only 64M memory there, and over 95% used: Mem: 60672K used, 1552K free, 0K shrd, 872K buff, 27736K Cached.
