The only thing that Apple fans lust for nearly as much as new hardware from Cupertino is a new update for their beloved Apple OS'. We knew that iOS 4.2 is set to hit after a beta for the OS surfaced for devs a while back. The OS was expected to hit iTunes today and geeks the world over have probably been spamming the software all day looking for the update.
We have some bad news; apparently, the OS update is delayed. The reason for the delay is that there was some sort of issue with WiFi with the iPad stemming from the update. It's much better to have irate users that couldn't get the update, than irate users with iPads that can't get online after updating so Apple made the right call here.
