My ipad2 glass screen was cracked when i accidentally dropped it.what should i do?help

First search the forums for information about cracked screens. There are a few mentions about being quite lucky when taking your iPad to an apple store and getting it traded out for free. You may get lucky.
If that particular store has already traded out some iPads recently they might not be so accommodating. I wish you the best of luck.
Don't forget to search the forums.
