Brett,
I've spoken to Asus about this. They say that the rev does matter. The customer service rep I spoke with said that rev 2 might work but it might not give all of the proper functionality. That's as definitive as I could get them to be.
Mine is also rev 3. I wound up sending it to their repair facility in Texas for replacement.
*Warning*: The experience has been horrible. First, the rep I spoke with on the phone told me that they would not sell me the part so I *had* to send it in. They didn't log it into their system until 2 days after they actually received it. It took another 7 for anybody to actually look at it. After 5 more days, I online chatted with a representative who told me somebody would call me within two days. I waited 4 before sending complaint emails to a couple of different places. They got back to me within 24 hours after receiving the first email. The first rep I spoke to (prior to sending in the device) said the new digitizer (LCD + glass) would cost $70 plus labor. The actual cost they wanted me to pay was $201, plus labor. I refused to pay that much and told them to send it back to me unrepaired.
If you try the rev 2, please post here and let us know how well it works for you.
Best wishes,
Rebecca
