I swear, it's like I'm playin' cards with my brother's kids or somethin'.
This isn't about whether you flashed your phone or not. This is about raging at AT&T because they haven't yet released GDR2 and, according to you, stopped caring about the 920.
I'm saying there isn't one shred of actual evidence they've stopped caring about the 920; all you've got is your personal rage-gasm against them. I'm also saying that unless anyone can prove otherwise, AT&T has yet to drop the ball on the GDR2 rollout; it was promised in August or September (depending on which reports you read) and it's still August.
Your personal phone is irrelevant. You seem to have an axe to grind over AT&T, but you do need to chill because lack of caring about, or failure to provide updates for, WP8 devices is not something AT&T can be tagged with. Yet.
