There is an issue or bug that has been discovered in the new Sidekick 2008 and the Sidekick LX phones with the video update. There is a currupted .3gp video file out there that has the potential to reset your entire Sidekick. Which just means that you will have to re-download everything and get all of your settings setback up. You can see an example of this happening in the video above.

To protect yourself from someone sending you this file in an email you can take the following precautions. Select Menu->Settings->Attachments->Remove Attachments then in the new menu simply tick the Multimedia box. This will prevent your emails from receiving a video file.
