This is a known issue and I would think by now RIM does to! I think with the popularty of this device it won't take long for the developers to adapt the apps to this device. I use dropbox a lot and it is also not working.

Doesn't have anything to do with RIM. The developers just need a little time to update their apps for the new OS. I'm sure we will see updates coming soon for many apps.
