Was there any other additions to iOS4.2GMb other then the wifi repair?? Using iOS4.2GM now with no problems and wondering if there would be any advantage to updating to 4.2GMb??
It is worth updating, no matter what! Having multitasking, folders, AirPrint and unified Inbox is worth it.
The question is whether to upgrade from GM to GMb.
I'm fine with the first GM; sticking with it till release. Might do a manual upgrade if itunes doesn't push it automatically.
