I absolutely suck at this.

VERY new BB user here. Here's what I'd like to accomplish. I'd like to chat on msn messenger on my phone, I'd like it to look kinda' sorta' like a chat session, and I'd like to not spend any more money since I already pay $500 per month to Verizon.

1. Is this possible? I keep thinking I can just find "MSN Messenger For Blackberry" or something, but I can't.

2. If it is possible, can you type REALLY REALLY SLOWLY when you tell me step by step how to make this magical mystical technology work?
