iOS 6 was released as beta yesterday and it is expected to be fully launched in fall. Fall season in 2012 starts on 22nd September. That means it should not be earlier than that.
In the new iOS 6, Siri was updated to be even more capable. It is now able to launch apps in which it could not previously. It now has more capability of searching for restaurants, more sports news and also movies. As we all here in Malaysia would have known, Siri is only capable of searching for weather conditions. Even the previous integration with Google Maps doesn't work either. So for us in Malaysia, nothing to cheer about in this upgraded Siri in iOS 6. Siri will also be available in the new iPad.
As we have heard thee rumors, Apple is now releasing its own Map. It has the capability of providing turn-by-turn navigation, live traffic updates as well as 3D imaging which Apple named it as Flyover. Obviously this replaces the Google Maps in the next generation iOS 6.
Apple did a nice tweak on the iOS 6 by allowing the users to dismiss calls with a swipe and sending pre-compiled SMS after rejecting a call. It is also capable of setting a location-based reminder for such purpose as well. Another feature is the Do Not Disturb feature in which the notifications/reminders/calendar will not no longer pop. You can set a specific time for the DND to happen. This is good especially when you're sleeping.
Facebook integration is also the newly available fine-tuned feature in the iOS 6.
All in all, it does seem like a lot of minor tweaks here and there on the iOS 6. The iOS 6 will be available officially for iPhone 3GS, iPhone 4, iPhone 4S, iPad 2, new iPad and iPod Touch 4th Gen.
