Apple released iOS 6.1 just early last week, and now the company has already seeded the first beta for iOS 6.1.1 to developers. It doesn't seem like a huge update at first glance, but there are some key improvements that are worth noting. Most importantly, Apple has worked on some major enhancements to its Maps app for Japanese users.
Included with the list of improvements to Maps in Japan include improved pronunciation of roads, optimized directions, added labels for intersections, interchanges, etc., updated icons for public buildings like fire stations and hospitals, more 3D buildings around Tokyo, and a few color tweaks within the app.
So, it looks like most the major improvements in the update are only applicable to Japanese users, with possibly some very minor bugfixes that could benefit all iOS users. Plus, the update could include a security block for the recent Evasi0n jailbreak, but that is yet to be discovered in this first beta.
Of course, Evad3rs team member MuscleNerd urges users who used the iOS 6.1 jailbreak to stay away from iOS 6.1.1 for the time being, even though it's not known whether or not the update patches the Evasi0n exploit. It's better to be safe than sorry at this point. Other than, it doesn't seem like a big update, and it's probably one that many iOS users won't notice in the long run.
