Captain Oblivious

My Treo has been misbehaving lately, so I've been looking at phones to replace it with. I saw several glowing reviews of the Pearl in the blogosphere, so I was debating between the Blackberry and upgrading to a newer Treo. Then I saw this. My eyes just about fell out of my head. So I hopped on over to Amazon and checked out the deal. Turns out it's for real. Total price? $49.99, with a $50 rebate. Yep, that's right, T-Mobile is paying me (yeah, just a penny, but hey, a penny is still coin of the realm) to take a Blackberry Pearl off their hands.

Unbe-freakin-lievable.

So I now have a question for the more knowledgeable Blackberry users: can I sync up my Notes calendar and/or my Google Calendar? I went with BIS, since work's not interested in giving me access to BES, so the calendar won't come as part of the deal. And, by the way, I assume one cannot use a Blackberry with both BIS and BES, right? I haven't been fully assimilated into the Crackberry hive mind yet, so I don't have all the answers I would usually have, but I couldn't pass up this deal and I wasn't sure how long it would last. Can any of the fully addicted among you fill me in? Point me towards the coolest Pearl customizations or apps or sites?
