is 247 official? because I'm pretty sure i read some people thought 246 was official.
Best bet is to run 232 and wait for the ota and just do that. at least thats what i'm doing.
The only "official" update will be the one that goes out OTA, at best the leaks are/were potential updates. Part of the reasoning if the leak will be the official one is how well the leak works and how long it has been out. If there's no new leak after 3 weeks, there's hope that the last one will be "the one."
That being said, .232 seems to be the best route at the moment as you have the option of going back to .905 if you need to.
