What is the Difference Between iOS 5 and iOS 5.1?

iOS 5 and iOS 5.1 are two versions of Apple's mobile operating system. While iOS 5.1 is an update to the iOS 5 platform, there are several differences between the two versions:

1. Siri in Japanese: With the release of iOS 5.1, Siri is available in Japanese, which was not available in iOS 5.
2. Photo Stream: In iOS 5, a photo added to "Photo Stream" could not be deleted. The iOS 5.1 update allows users to delete images that have been added.
3. Camera Shortcut: In iOS 5, the camera shortcut was not always visible on the lock screen. iOS 5.1 resolves this issue, making the camera shortcut consistently visible.
4. Battery Life Issues: iOS 5 was criticized for battery life issues, which were addressed in subsequent updates.
5. Audio Drop Issues: Audio occasionally dropped during outgoing calls in iOS 5. This issue has been fixed in iOS 5.1.

Overall, the main differences between iOS 5 and iOS 5.1 are related to language support for Siri, improvements in photo and camera functions, and bug fixes.
