Among the reported bug fixes in iOS 6.0.1:

  • Improved Wi-Fi support
  • Camera flash sometimes not going off when photos are taken
  • Fix for horizontal lines appearing on the keyboard
  • A bug with Microsoft Exchanges meetings getting cancelled
  • A bug affecting cellular data, and cellular data used with iTunes Match
  • A Passbook security via the lockscreen issue

Could this be the fix we've been waiting for? I'm also hoping for drastically reduced iTunes Match cellular usage.
