Palm is now sending the webOS 1.0.4 firmware to its Pre users. Apparently, the new update fixes a number of security issues, which seems to have been discovered thanks to Townsend Ladd Harris (a Pre homebrewer). Palm has thanked him publicly, and the company is now inviting everyone who would want to help make the platform better and safer. Unfortunately for application homebrewers, Palm has made installing apps via e-mail impossible (for now). This is also an important security measure, since who knows what malevolent content might be sent to you someday. Still, apps that you have already installed this way will continue to work.
