Have you tried appworldvendorsupport@blackberry.com ?
Sent email on the 11th and Ryan answered on the 18th. I suppose it's possible a few App World staff might have been at Dev Con.
I get the impression App World has been more successful developer sign up wise than RIM expected and they're probably scrambling to staff appropriately. The problem of course, is that during the initial ramp up phase for new staff, service can actually deteriorate as existing staff mentor new entrants.
It's frustrating but so far I've always had decent service. You just have to wait longer than expected.
One things for certain, it's well worth testing your apps thoroughly before uploading. It takes weeks to deploy even minor upgrades.
