1st thing to do is reserve a room at the rehab. 2nd thing to do is to search for the thread on 1st 10 things to do with your BlackBerry. Hope this helps.
chef, you best bet is browing through these forums and you'll be surprised at how much info you can pick up...try the device specific threads as well, alot of good stuff in there
Nobody has really answered your question so I'll give you my opinion. The BB is great communications and information tool. So setup some email accounts on it and pick up Viigo which is a great RSS feeds application and setup some feeds in it to get news and information. The best thing about Viigo is it is FREE. After you do that you'll probably start getting a pretty good idea of what you want to do with it. There are a lot of applications you can install on it but remember it has a finite amount of memory so keep that in mind.
