If anyone wants to update their phones, I STRONGLY suggest updating a 2.3 phone (v20a) and not a 2.1 one (v10D). You cannot rollback a 2.1 phone upgraded to 2.3 (THANKS LG! GREAT JOB YOU'RE DOING THERE).
As for what's supposed to be released with v20B, mostly a bugfix edition from all my communications with LG. Of course, I was only partly expecting the update to be on time today. I give it until the end of June before we see signs of an upgrade...
Raskal13, I just tried to look for an update, none come up for my v20a phone...
Android Bob, also, the update will come through the LG update tool as specified above. I'll also post the ROM here once I can download it.
