getting the jar/jad to your mobile without WAP Download
For Nokia devices you will need a program such as the Nokia PC Suite. At least S40 3rd Edition also allows transfer of jar file using standard infrared/bt uploads (tested on Nokia 6233).
For Motorola devices with a Memory Card (SD Card) you may put the jad and jar into the kjava directory of the card (it is a hidden directory!). Then select 'install new' in 'Games and More'. Now the game should show up (it worked on a Motorola V980)
On other devices it may be suitable to just transfer the file via any means (bluetooth, IR, cable) to your mobile
