I have found out what the major issue is if you are using a "silver" frame digitizer. These are the most common on the market that we have been finding. The problem is similar to the mini, but different is the sense that the tape you use needs to be placed in between the cables and the glass behind where the cables attach. The mini you place the tape over top of the cables so as it does not come in contact with the frame. With the AIR the same thing is needed, but additionally placed between where the cable feeds into the digitizer and where the glass on the outer edges meet it. You have to be VERY careful as to not "over bend" the digitizer cables and you must tape it AS CLOSE to the base as possible. Hope this helps... took us about 3 hours of playing around to realize.
