No, this isn’t some new fancy device that’s going to kill the Sidekick. It’s a corrupted 3gp video file that has the potential to hard reset a Sidekick with very little user interaction that’s out in the wild. That’s right, hard reset, as in wipe out all of your data and force you to redownload it from Danger’s servers. Luckily with the way the Sidekick is designed you won’t lose anything, but it’s still an annoyance to have to wait for all your email, settings, etc to download. It’s also a really nasty trick to play on someone you don’t like.
This was first posted in the PBD forums under a thread titled “Virus In Email?! Important!! Read!!”. I know, my first thought too was, “yeah right, Sidekicks don’t get viruses”. Technically this isn’t a virus, and it isn’t even malicious in intent. It looks like it’s just a bug with the way the email application handles a corrupted video. Needless to say though, it is a serious bug that Danger will hopefully fix in an OTA quickly. This currently affects the new Sidekick 2008, as well as Sidekick LXs with the video OTA.
Want to protect yourself from this sort of crash? In your Email, go under Menu->Settings->Attachments->Remove Attachments of these types, and check “Multimedia”. This will remove any movie files that are attached to emails sent to you, including this nasty one.
