It is now more than a half a year later and it seems that all of the bugs have been removed from the Android 2.3 update which will roll out to LG Optimus S users starting on Wednesday via a staggered OTA process. It will take up to 21 days to complete sending out Gingerbread to every Sprint LG Optimus S user. So if you don't get the update Wednesday, don't panic because it is coming.
The update will fix the bugs listed above and will also repair a problem with the volume on voice calls, update the color scheme (darker notification bar, black-based menus), add a new virtual keyboard (supports multi-touch input and a smart auto-correction function), improve cut-paste function, add a new integrated application for easier access to downloaded files, update the camera application and add applications for power management and a task killer. Of course, the update installs Android 2.3 on the phone. The new software version is LS670ZVJ.
