I just got a Blackberry 8100, and I downloaded Windows Live Messenger. It works fine if I sign in with a hotmail account, but if I try and change the domain from "@hotmail.com" to "other" I get this error: Uncaught exception: java.lang.ArrayIndexOutOfBoundsException.
EDIT: While we're at it, how do I record voice? My girlfriend is always sending me voice notes, and I have no clue how to answer her.
