Coming this fall, iOS users will be getting a an upgrade to their mobile OS, one that adds over 200 new features to the already popular line of iDevices. With this many features, it might be hard to get a handle on just how some of these new features are going to affect your experience.

In this TechTip, I’m going over the top 5 new features in iOS 5 that can change the way you use your iDevice.

iMessage

Do you want to cancel your text messaging plan because it’s too expensive? Okay, you probably won’t be able to do that right away with iMessage, but it might be enough to subscribe to a lesser plan. With iMessage, all iOS 5 devices will be able to send text, images, video, locations, and contats with all other iOS devices, over Wi-Fi or 3G, for free. Data rates will still apply, of course, but you’ll be free from the limits of messaging plans. This is a big move for Apple to get you, your family, and your friends to all use iDevices so nobody will be left out of the conversation.

Notification Center

How many times have you done this? You pull out your iPhone, you swipe to unlock and just before it unlocks, you see you have a notification, but it’s too late; you’ve already swiped and the message is gone. Unless there’s a badge to let you know where it came from, that message is gone. To cure this problem, Apple’s borrowing an Android-style method that puts all the notficiations in their own app called the Notification Center. All notifications will be logged here, and you’ll be able to see the most recent notifications on the lockscreen at a glance.

Camera App

I’m sure you don’t have to try hard to imagine this next scenario: you’re witnessing something momentous, you remember your iPhone is also a camera, so you pull it out and get ready to snap a photo, but you have to unlock the screen, touch the Camera app, and wait for it to open. It’s not something that ruins usage of the phone, and it’s on par with having to dig out a dedicated point-and-shoot digital camera, but it still leaves something to be desired. With the new and improved Camera app, you’ll be able to start it right from the lockscreen. Better than that, you’ll be through with doing that awkward maneuver you do when trying to snap a photo while touching the button on the touchscreen, because the Volume Up button will be the new capture button.

iCloud

There are more than just photos and videos stored on my iPhone. There are the many other valuable pieces of information that include phone numbers, email addresses, and appointments. iCloud is going to make managing this extremely simple at zero cost and with zero effort. Almost everything is going to be backed up to Apple’s own servers where it will be accessible by all of your registered iDevices. This will make it easy to avoid the embarrassing mass emails, tweets, or Facebook posts that tell everyone you lost your phone. There is much more to iCloud than this, but this feature alone makes it invaluable to me. The best part is that it is replacing MobileMe, a service that used to do less for nearly a hundred dollars.

PC Free, Over-the-Air Updates

Okay, I cheated, these are two features in one, but they should both be under the heading “cutting the cord” because that’s what these two are about. With PC Free setup, iDevices will no longer need to be plugged into a computer to initialize. Maybe you’ve only set up your phone once and you never plugged it in again, which is a surprisingly common scenario. With Over-the-Air Updates, you’ll be getting the latest firmware updates without having to plug in your device. You’ll still have to plug your iDevice in one last time to install iOS 5, but that could be your very last time! Removing this barrier to entry makes iOS devices even more accessible to users with very limited computer access.

With over 200 new features, these few functions barely even scratch the surface of iOS 5. Be on the look out this fall for the update.
