What's not to love about iOS 5?

So the new iPhone 4S came out last week, and sales for this iPhone launch more than doubled that of the iPhone 4, with over 4 Million iPhone 4S's already sold! And although there are some distinct functions that only the iPhone 4S can do, it's operating system iOS 5 can be uploaded on the iPhone 4 or iPhone 3GS (those are the two phones my wife and I have... so I'm aware of exactly how iOS 5 functions on both of them).

iOS 5 is a big deal! Before going into some of iOS 5's great features, we'll make a small list of the advantages you'd have with the iPhone 4S in comparison to the older generation iPhone's.

1. 8 megapixel camera/1080p video camera
2. The A5 chip (same speed as the iPad2)
3. "Siri" - one-of-a-kind voice recognition software

Those are the major differences.... all the other differences are functions that come along with iOS 5's software and these are fantastic!

1. iCloud (more on this in a moment)
2. iMessaging from iOS 5 device to iOS 5 device (text on iPod or iPad)
3. Improved Camera and functions and Photo Editing
4. Quicker access to any alerts from lock screen
5. Newstand
6. Reminders

Now descriptions in more detail on each of these.

1. iCloud

iCloud stores your music, photos, documents, and more wirelessly pushes them to all your devices. Automatic, effortless, and seamless --- it just works. iCloud is so much more than a hard drive in the sky. It makes it quick and effortless to access just about everything on the devices you use every day. iCloud automatically and securely stores your content so it's always available to your iPhone, iPad, iPod touch, Mac, or PC. It gives you access to your music, apps, latest photos, and more from whichever device you happen to be using. And it keeps your email, contacts, and calendars up to date across all your devices. No syncing required. No management required. In fact, no anything required. iCloud does it all for you.

2. iMessaging from iOS5 device to iOS5 device (text on iPod or iPad)

iPad and iPod touch join the conversation. With iMessage, Apple has created a new messaging service for all iOS 5 users. You can send unlimited text messages via Wi-Fi or 3G from your iPad, iPhone, or iPod touch to anyone with one of those devices. iMessage is built into the Messages app, so you can send text photos, videos, locations, and contacts. Keep everyone in the loop with group messaging. Track your messages with delivery receipts and optional read receipts, see when someone's typing, and enjoy secure encryption for text messages. Even start a conversation on one of your iOS 5 devices and pick up where you left off on another.

3. Improved Camera and functions

Since your iPhone is always with you, it’s often the best way to capture those unexpected moments. That’s why you’ll love the new camera features in iOS 5. You can open the Camera app right from the Lock screen. Use grid lines, pinch-to-zoom gestures, and single-tap focus and exposure locks to compose a picture on the fly. Then press the volume-up button to snap your photo in the nick of time. If you have Photo Stream enabled in iCloud, your photos automatically download to all your other devices.

4. Quicker access to any alerts from lock screen

You get all kinds of notifications on your iOS device: new email, texts, friend requests, and more. With Notification Center, you can keep track of them all in one convenient location. Just swipe down from the top of any screen to enter Notification Center. Choose which notifications you want to see. Even see a stock ticker and the current weather. New notifications appear briefly at the top of your screen, without interrupting what you’re doing. And the Lock screen displays notifications so you can act on them with just a swipe. Notification Center is the best way to stay on top of your life’s breaking news.

5. Newstand

Read all about it. All in one place. iOS 5 organizes your magazine and newspaper app subscriptions in Newsstand: a folder that lets you access your favorite publications quickly and easily. There’s also a new place on the App Store just for newspaper and magazine subscriptions. And you can get to it straight from Newsstand. New purchases go directly to your Newsstand folder. Then, as new issues become available, Newsstand automatically updates them in the background — complete with the latest covers. It’s kind of like having the paper delivered to your front door. Only better.

6. Reminders

Next time you think to yourself, “Don’t forget to...,” just pull out your iPhone, iPad, or iPod touch and jot it down. Reminders lets you organize your life in to-do lists — complete with due dates and locations. Say you need to remember to pick up milk during your next grocery trip. Since Reminders can be location based, you’ll get an alert as soon as you pull into the supermarket parking lot. Reminders also works with iCal, Outlook, and iCloud, so changes you make update automatically on all your devices and calendars.
