Microsoft/Danger has started rolling out an OTA (Over-The-Air) update to all Sidekick users. This update will not make any changes to your device that you’ll be able to see. It’s intended to fix some behind the scenes stuff so that “all Catalog application data will now be more securely backed up in the Microsoft / Danger systems.” This is NOT the Sidekick LX 2009 OTA I posted about earlier, which I assume is on indefinite hold until everything gets sorted out. It’s assumed that this OTA is rolling out to all Sidekick devices. Let us know in the comments if you received the OTA, which device you’ve got, and when you got the update.
