Oh, forgot to mention some handy apps;
jMirc - IRC client
vlingo (free)- speak into your phone and it will translate into a TXT msg for you.
Profiler($) - allows you to set predetermined times for your BB to switch your Profile. Ex. Auto will switch to Silent at midnight so u sleep uninterrupted and switches back to Loud at 7am when you wake up.
Not Now ($)- can automatically send a SMS to callers who u don't answer in time. Ex. You turn off ringer during a Dr appt. U setup a message that says "in w/doctor until 3pm - will call ASAP".
Ascendo Data Vault ($) - like the standard Password Keeper on steroids! I love it.
beyond411 (free)- enter your home adress and then search on a resturant or store. Instant phone number and can even give you a yahoo maps location.
