I'm not entirely familiar with the Nokia 770's file system, but my understanding is that the flash memory is shared between the main file system and the working memory used by running applications. If this is true, then does installing additional applications (which can only be installed on the internal flash memory, not a RS-MMC card), doesn't this reduce the amount of available working memory?

On the same note, is it possible to uninstall other programs (like the crappy email client or the news reader) to free up memory? Has anyone tried this? Does it work? Or are the partitions pre-sized in the flashed filesystem (possibly requiring tweaks)?

Are there any custom flash images that already exclude some of the unnecessary applications?
