I just replaced the back and digitizer to an ipad 2, here is the best picture I took of the ribbon. Hope this helps (if it isnt too late!)

Impossible to do, you must buy a new digitizer.

Thats kinda steep, 149. You can find the same part on ebay for 75 with adhesive, button, camera holder included. I just completely rebuilt an ipad 2, I buy my parts from this company called usmobileparts out of california. Never had any problems with the products. Also, it would be a good idea to buy the plastic bezel and replace this also, it is only a $6-10 part and will make your life a whole lot easier. Cant access ebay from work but just search the seller usmobileparts
