If you just want a ready-made version of the World English Bible for Bible+, get the latest release from the WEB for Bible+ file area.
gbf2pc is a tool to convert General Bible Format files, such as the World English Bible's source into BibleConverter format for use with Bible+ for Palm OS.
Usage information can be found in the README included in the source.
If you find having the WEB on your Palm useful and wish to support it, please don't send the developers any money. We have the easy step in this whole process.
Instead, consider sending a donation to Rainbow Missions, who works on the World English Bible.
