We want to remind you that Palm had released an update for its webOS before the actual launch of the Pre. So, if you have finally gotten your hands on the hot smartphone, but still have the original version 1.0.0, you can now download the 1.0.2 update and see what's new. It supposedly makes the system more stable and adds a new alarm clock, since it seems people have experienced data loss and had to use the Palm Profile backup utility to restore their settings. You can update your Palm Pre through the Update option, under the programs menu and you won’t have to quit your work while the 67MB update is being downloaded.
