As the phone makes its way into the marker, users have started to notice some of the hidden features of the iPhone 4S that were not well known before. For example users can now have their customized keyboard shortcuts saving them from the mess of incorrectly tapped words or situations where they have to spell difficult or long words. This could also be used as a prank on your buddy's iPhone.

On that note, perhaps the biggest of all is the addition of over-the-air updates, which obviate the need to tether your iPhone to a computer for syncing. But there's a lot more under the hood with this upgrade, and we think users should be excited to plug in their iDevice one last time. iMessage also adds a new way to keep in touch and a way to circumvent your carrier's monthly allotment of messages. On the surface, this idea doesn't sound so bad. In fact, it sounds rather convenient for those on the go, but that's all relative as to how the updates would implement. As it stands now, updates require the phone to not be in use and then a full restart follows the software installation. I can't imagine what it might be like if iOS 5 needed to restart every day after seemingly insignificant updates. However, for anyone that runs OSX knows, there are few updates that don't require a  restart!

A few improvements simply make the user experience easier, like Twitter integration in the major Apple apps, basic image editing tools for the camera, and a Notification system paired with reminders that keep you informed with a glance at your Home screen. Smaller upgrades abound, of course, some of which we've listed here. We haven't found all the "Easter eggs," though, so as you find other changes let us know in the comments.

Defect 1: calendar option is too little

Although you can temporarily hide part of the calendar reminder, but the event in the center notification can't hided, including all events that don't require frequent attention will also constantly remind, inform center seems to become the center of harassment, as users can not put DVD movie onto ios 5, unless we need to use the mac iPad converter to do that. As iPad is getting more and more popular in our digital life all over the world, then many problems related to iPad came out. The most common issue for iPad users is that how to convert DVD to iPad for Mac. The solution is dvd to ipad converter for mac. So how to choose a right and proper DVD to iPad for mac software for us becomes an hot topic.

Defect 2: Don't feel complete iMessage

Defect3 : iOS 5 information capacity is too small

IOS 5 information of maximum size is 15 MB, and whatever your equipment hard drive is 64 G or 16 G, this will not changed, The capacity limit includes your all sent video and pictures, so for many people, the cap is too small. And if you reach the maximum information, then you have to take the time to clean up your message box, quite boring.

It was more like a kind of hate iron, iMessage always lets a person feel not play its potential, why not add group chat functions? Why send E-mail with good intelligence pictures and videos? Text input box next to door of camera button should have more features, and should have other things to assist you to input your position, near the information such as the photos, what need to improve is too much, and it has been standing still. Position memo of iOS 5 is a very useful auxiliary function, it may according to what position you set to remind you, but it is the address of the contact support the use as a memo address information, and that has made just to remind yourself to ATM machine to get the money to the ATM user added to contact, this was too much trouble.

Available for free, iOS 5 will be compatible with the iPhone 4S, the iPhone 4, the iPhone 3GS, both versions of the iPad, and the third- and fourth-generation models of the iPod Touch. Keep in mind that the quality of iOS 5 may vary by device. When Apple released iOS 4 last year, many iPhone 3G users complained of degraded device performance after they downloaded the update (one group even filed a lawsuit). Apple mostly fixed the issues with the release of iOS 4.2, but we'll be taking a close look as to how iOS 5 fares on the 3GS.

On the surface, this idea doesn't sound so bad. In fact, it sounds rather convenient for those on the go, but that's all relative as to how the updates would implement. As it stands now, updates require the phone to not be in use and then a full restart follows the software installation. I can't imagine what it might be like if iOS 5 needed to restart every day after seemingly insignificant updates. However, for anyone that runs OSX knows, there are few updates that don't require a system  restart!
