With the Sidekick Outage debacle behind us, Microsoft/Danger is making sure the data loss “incident” doesn’t occur again. Reports are coming in that Sidekick LX 2009 users are receiving an Over-the-Air (OTA) Update today (OS 5.0/270115). According to Hiptop3, the OTA is a combination of bug fixes and the new Mobile Backup support T-Mobile announced a while back. The OTA should also rectify problems such as freezing and crashing, many Sidekick LX 2009 users incurred. The OTA might cause your Sidekick to hard reset, so there is no need to worry, since all your data should be backed up to Danger’s servers. After the update, Sidekick LX 2009 users can feel secure, since your address book will be backed up to T-Mobile’s servers as well! Some screenshots of Mobile Backup Support in action after the jump! Let us know if you’ve received the OTA and whether or not you’ve noticed any other significant changes in the comments!
