I assume you formatted the card using the File Manager, in which case the N800 will format the card using FAT16 - 2GB is the maximum volume/partition supported by the FAT16 filesystem. The N800 also understands FAT32 and this is what your PC used to format the 4GB card so when you re-inserted it back into the N800 the full card capacity could be accessed by the N800.

Basically, the N800 needs to use FAT32 when formatting > 2GB partitions, and FAT16 <= 2GB.

Until this issue is resolved you will have to continue formatting your card in your PC to get the maximum capacity, or use mkdosfs in xterm.
