What is the use of iOS 6.0.1?

What is the use when there are no features added into iOS 6.0.1? It's such a waste of memory on the iPhone.

Ok there are some new features like:
1. 3D maps
2. Facebook integration
3. Better Siri
4. Shared Photo Stream
5. Camera With Panaroma
as a conclusion u shud update…

3D maps? You mean those everyone is making fun of and which caused one of the top level managers to get fired? A 'feature', nevertheless.

facebook 'integration' laughing my *ss off, now that's a feature. How about a simple app that can do that?

better Siri - another LOL, it was supposed to be the 'big shot' in iOS 5, and is mostly useless (and needs constant internet connection anyway).

Upgrade if you want to, but as long as you're happ with the current iOS, stick with it. Something that's 'new' is not always better.

A lot of users are facing WiFiproblem with their iPhones and iPads running iOS 6. That is the main reason Apple has released iOS 6.0.1 with bug fixes for Wi-Fi problems. If you are experiencing Wi-Fi related issues, I would recommend to update your device to iOS 6.0.1.

The.0.1 tells you that it is a minor update that will fix problems some people have had. These being…

• Fixes a bug that prevents iPhone 5 from installing software updates wirelessly over the air
• Fixes a bug where horizontal lines may be displayed across the keyboard
• Fixes an issue that could cause camera flash to not go off
• Improves reliability of iPhone 5 and iPod touch (5th generation) when connected to encrypted WPA2 Wi-Fi networks
• Resolves an issue that prevents iPhone from using the cellular network in some instances
• Consolidated the Use Cellular Data switch for iTunes Match
• Fixes a Passcode Lock bug which sometimes allowed access to Passbook pass details from lock screen
• Fixes a bug affecting Exchange meetings

It updates the existing iOS files and does not take up any more space.
