I've already tried to call attention to this a couple of times in this thread, maybe third time's a charm. I found the following bug:

Palringo and Facebook Instant Messenger (FIM) don't connect properly. Palringo gets stuck going back and forth between a "connecting" dialogue and "reconnect pending". FIM just gets stuck on "connecting". I've tried connecting on both verizon's network and via my work's wifi and my home wifi. None have worked. Any thoughts on why that might be?

Note that I've tested this on the 23547 build, both on the MaxManila build and on the Titanium build.
