Dell Streak's screen cracked - what are my options?
Found this on the Dell Forums:

My Dell Streak Gorilla Glass broke today...i was coming back from eating dinner with the family and walking up the stairs the DELL STREAK fell out of my jacket pocket....and bam crash boom..it has  all types of cracks and glass pieces all over the place...
SOLUTION....
I immediately called dell customer care to see what my options where and the CSR...WAS JUST GREAT. She went out of her way to take care of all my issues and she did...before i knew it she had ask for my service tag on my Streak...and some personal info and the next thing you knew it was getting a email confirming that my NEW DELL STREAK was on the way....UPS TRACKING # i was amazed....how quick it was being resolved....THANK YOU DELL

You can also probably get replacement screens off ebay, and I am sure there are youtube video tutorials on how to replace the screen.
