Anyone who has installed any homebrew app via the email method will notice that this method is obsolete (no longer possible) after the WebOS 1.04 update. Here are instructions for another installation method that still works.
1) Install SDK (download here:
http://preinsiders.com/home/2009/06/...ed-to-the-web/ )
2) use konami code to put Pre in dev mode (see post #2)
3) reset Pre
4) Connect Pre to PC in "Just Charge" mode
5) Drag .ipk file for your homebrew app onto Program Files>Palm>SDK>bin>palm-install.bat on the PC (a cmd prompt will pop up and after this you should see the app icon in your programs on the Pre)
Here is a nice homebrew app for you to test with. It is actually a sweet little Google translator app made by Roar over at PreCentral. Thanks to Roar for the nice app and PreCentral for hosting the homebrew party.
