Just discovered something weird with the Social Feeds app:
I removed the various IM and Twitter applications because I use an all-in-one app instead. Come to find out, that's not fully OS6 ready, so I removed that and reinstalled the separate apps again .... and they did not reintegrate with the Social Feeds app like they were out of the box. Perhaps the versions in App World aren't the same as what's preloaded; I'm not sure.
I'm about to wipe and install the latest OS6 leak (god I hope it fixes the handset audio problem), I'll report back with the IM version numbers and see what happens.
The versions of Facebook, Twitter, and the various instant messaging apps that come pre-loaded are a newer version than what's in App World. If you nuke those and then install what's in App World, you're hosed. You have to use the version that comes with the OS to integrate with Social Feeds.
Way to go boogering that one up, RIM. Sheesh.
Disclaimer: I'm getting this from the leaked .161 OS. I didn't waste time reinstalling the version that came came with the device (.141)
