I just realized that my N800 cannot be installed any programs after upgrading to os2008 43-7.
I believe it happens because of dual-boot.
Without carefully thinking, I went to flash booting and upgrade the OS in flash partition.
As you can imagine, the dual-boot menu has been wiped out.
Now, I have very fresh N800 (none of useful applications in the flash partition).
I may decide to strictly boot with flash partition from now on.
The next problem is since the size of flash is very limited, how to install applications on the internal memory.
