I'm trying to minimize cost as much as possible-I would like to just replace the screen-where can I find ones (does RIM sell them online?)

or are there any courses of action with at&t? I am eligible for upgrade on 6/24, but I do not know the discounts available (I really like this model, I would just stick to it)

I do not have insurance. I dropped it (so so sad) and it cracked.

thanks for you help! any advice would be appreciated.
