iOS 5 is the next mobile operating system made by Apple. If you want to know how to download it, read the post from October 16. Here is my review of iOS 5.
1. iMessage - iMessage is a texting app and it allows you to text between iOS devices. The layout of the app is very similar to the Messages app on the iPhone. You can use it send photos and contact cards (vCards). This is very useful for contacting family members.
2. Push Notification Center - Push Notification Center allows you to access all your notifications in one place. In previous versions of iOS, you would have to tap either "Close" or "View." Now, they just appear as cubes so, they don't interrupt you. In the Lock Screen, you can slide your finger across them and the app they came from opens up. To open the center, slide your finger down from the top of the screen. I like this because I have a lot of notifications.
3. Safari - Safari in iOS 5 allows you to do a couple of things. On every device, Safari has iCloud support and Reading List. On the iPad, they built tabbed browsing. You can move tabs around by tapping and sliding. You can get rid of a tab, by tapping the X. I like how Apple got rid of those funky windows on iPad.
