iOS 5.1 Update Adds 4G To AT&T iPhone 4S, Improved Battery & More

Apple has released iOS 5.1 software update today for iPhone, iPad and iPod Touch. The update brings Japanese language support for Siri and one significant change to the iPhone 4S on AT&T. iOS 5.1 has updated AT&T network indicator to show the "4G" status symbol instead of '3G' when ever your iPhone 4S is hooked up to AT&T HSPA+ 4G network. Although you'll likely be seeing that 4G status all the time, you're internet speeds won't actually be any faster then they are now.

- Japanese language support for Siri (availability may be limited during initial rollout) 
- Photos can now be deleted from Photo Stream 
- Camera shortcut now always visible on Lock Screen for iPhone 4S, iPhone 4, iPhone 3GS and iPod touch (4th generation) 
- Camera face detection now highlights all detected faces 
- Redesigned Camera app for iPad 
- Genius Mixes and Genius playlists for iTunes Match subscribers 
- Audio for TV programs and films on iPad optimized to sound louder and clearer 
- Podcast controls for playback speed and a 30-second rewind for iPad 
- Addresses bugs affecting battery life 
- Fixes and issue that occasionally caused audio to drop for outgoing calls
