Hi,
I'm very sorry, but three20 its *NOT* coming alive again. I just announced, that three20 is no longer maintained. There's effectively nobody taking care of it. The pull requests I just merge were only to clearly express that fact.
Three20 is still usable as it is, but it will no longer receive any updates until someone steps up to start taking care for it.
I would suggest to not start a new project using three20 and I would suggest to think about how it could be removed from app that should live on.
Regards
Tono
