*Update: Looks like this may be the case for Bold 9650 users as well. Make sure you're running the last official OS from Verizon and see if the update is available to you.
A few users have been reporting in today and it looks like OS 6 may be on the way down the pipeline from Verizon. Justin snagged us this screencap of his 9330 where it looks like OS 18.104.22.1681 is available for an OTA update. Still no sign of OS 6 on Verizon's download site, but it's not unlike them to make the wireless update option available ahead of time. If you have a 9330 and are running an official OS, head to the wireless update option and let us know if it's showing for you. Thanks Justin!
