Next generation of Apple mobile operating system iOS5 will soon be available for iDevice users. “We’re taking iOS to a whole new level”, that’s Apple’s slogan. It imports a lot of Cydia (jailbroken) software’s and existing App Store apps features in this version. Let’s see what’s new for this new iOS:

• Notification Center: All SMS, Notifications, Mails, Reminders & Calendars will be shown in this notification center. This idea is similar to LockInfo (Cydia software).
  
• iMessage: Messages can be sent from & to iPod, iPad & iPhone via WiFi or 3G. The idea is similar to WhatsApp (App Store software).
• Newsstand: News can be accessed directly from iOS menu. Users can subscribe news and receives updates automatically. This idea is similar to Android’s news widget in dashboard.
  
• Reminders: Reminders finally added to Calendar. It will work with iCal, Outlook and iCloud. Various mobile operating system has similar features.
  
• Twitter: built-in Twitter is added to provide instant tweeting from Phone. Um… why not add Facebook too?
• Improved Camera:  Camera has changed a lot: (1) it can be accessed in Lock screen; (2) Pinch to zoom, tap to focus, grid lines, exposure lock; (3) press volume-up button to take photos. These features are not hard to be found in existing App Store camera apps. Through iCloud, photos can be shared to other iDevices.
  
• Photo editing: Photos can be edited without leaving Photos app. At this moment, only few modifications such as photo cropping, red-eye removal and color tuning are allowed. We hope that more filter effects can be added. These features can also be found existing photo editing software in App Store.
• Safari: Safari now goes full-screen & tab-bar browsing is finally available. Users can also save page to Reading List for later reading. This feature is similar to FullScreen for Safari in Cydia software.
• Computer Free: This is really a breakthrough of iOS technology. Updating, Backing up & Restoring iDevice do not require to connect it to iTunes, instead, through iCloud via WiFi.
• Improved Mail: Mail can now be formatted (bold, italic and underline fonts & indent texts). Important mail can be flagged. Searching mail now includes mail content. With iCloud, there will be a copy of emails in the cloud.
• Calendar: Year view & Week view are available. Events can be dragged to rearrange. iCloud also allows users to share calendars to friends.
• Game Center: Discover new games without leaving Game Center.
• WiFi Sync: Wireless Sync is now available once you plug it into a power adapter. Contents will be automatically backup and sync with computer.
