So that list of ISIS supported devices was released and I noticed the T-Mobile GSII was on it but not the AT&T one. Did they just give up on trying to allow us to take advantage of NFC?
AFAIK, the official ATT ICS 4.0.3 hasn't turned "on" the NFC yet. Until they do that, ISIS is out of the question. T-Mobile just released an update to enable NFC; therefore, their SGSII is the only one qualified ATM.
