Apparently the T-Mobile LG Sidekick LX 2009 has received a new firmware over the air and is OS version 5.0/270115, reports an article over on hiptop3, although any detail on the update is extremely thin.

Word has it that the main thing with this OTA update is support for backing up contacts to T-Mobiles Mobile Backup service, and once the update is complete the user should hopefully experience less crashes.

No doubt the firmware update also includes several bug fixes for improving the users experience as well. Apparently the OTA update may cause your Sidekick LX 2009 handset to do a hard reset but don’t worry it’ll all come back apparently.

Well let’s hope it all comes back or we will be seeing yet another round of data loss like the previous issue with sidekick data. Still if you are one of those with a Sidekick LX 2009 and have problems with the update feel free to drop us a line.
