Answer to: iPad 3rd Gen Digitizer the same as 2nd Gen?The board sockets (connectors) are the same. The iPad 3 digitizer cable is longer though. So, as stated above, you can use the iPad 3 diggie on an iPad 2 with a couple of folds on the longer cable. However, you wouldn't be able to use an iPad 2 diggie on an iPad 3. The cable just isn't long enough. IndyElectronix
Answer to: No digitizer after glass replacement?I had the same problem as well. Turns out that the little pins on the digitizer connector on the motherboard come out VERY EASILY. I'm in the process of looking for a replacement connector. You may have the same issue. Put a magnifying glass on that connector and make sure all the female pins are there.
