I've heard that the maker of eFlyBook would send firmware updates via mail on CD-ROM every 2 months or so, and that you could also use an included PC tool to download the upgrade from the Net. You would put the upgrade on the SD card of the eFlyBook which would then process it.
Now I think that's very interesting news for certain people who like to get custom data on their device
Could anyone who has the eFlyBook confirm this?
