We all have to wait for Pantech and ATT to develop / fix their bloatware (oohhh... i mean their custom software ... nah .... bloatware is right!) ready for release on Google play. Basic JB is already out ... and the drivers are already available for ICS! The only other reason maybe ... to promote their new models to be sold with JB .... as adding JB update to an older gen model(s) (relatively older) may reduce profit for the newer models? Other way to get JB update -> Root and install custom ROM. (Please check xda website) Cheers!
