Apple Begins Testing iOS 6.0.1 With Carrier Partners
Apple has reportedly begun testing iOS 6.0.1 with carrier partners in the U.S., reports BGR. The update is said to fix a screen glitch but that causes horizontal lines and a bug in which the camera flash doesn't go off.
In addition, the new software will improve Wi-Fi support, fix cellular data not working in some cases, add a consolidated cellular data switch for iTunes Match, fix a bug that allowed access to Passbook pass details from the lock screen, and also finally fix the bug that caused Exchange meetings to be unexpectedly cancelled for the entire calendar invite group.
Finally, the site says Apple just began testing iOS 6.0.1 which makes it unlikely that iOS 6.1 will ship before the holidays unless there is a build just for the new iPad.
