Soon almost a full year has passed, and we, the Lumia 920 users, can still NOT choose our own audio file for incoming messages.
When will this be available?
Not just us 920, but all WP users. It's been an issue well documented. They have to be aware of it. Though from Daniel's articles it could be on the back burner while doing things to grow marketshare. We can only hope that it's coming with Blue. I don't think there's much chance of GDR3, but I would love to be wrong on that.
