Apple has just issued iOS 6.1.1, a bug-fixing update aimed at the iPhone 4S specifically to address issues around cellular issues on 3G connections for some European carriers, per the release notes. The update had been in beta for only five days, which is a much shorter cycle than Apple usually goes through for new iOS updates. The new release is a different one from that already in testing, according to Apple, which addressed Maps fixes for users in Japan.
