Top 5 Controversial Features of iOS 4.0

iPhone 3GS and iPod Touches both can be upgraded to iOS 4.0, but there are still 5 controversial features of iOS 4.0.

Now, iPhone 3GS and iPod Touches both can be upgraded to iOS 4.0, the following are the assessment of the features of iPhone OS 4.0:

Infancy Multi-tasking

Apple only gives developers little time to achieve multi-task and you can only use the original multi-task processing, which may not meet your needs. Besides, not all the programs are running in the background at the same time, which may occupy resources and waste battery. Apple allows the third-party programs to run in the background and all programs can save the state in the fast switching with ease.

You can switch from one program to another, such as switching from a game program to the GPS program, but this can not exactly guarantee that you can switch back the game program after the departure. In fact, there is a crack application named Backgrounder in the background, which is easier than the multi-tasking of iOS 4.0.

Be Careful with Wallpaper

The interface designers of iPhone OS revealed that iOS has larger capacity and greater responsibility. It will be very ugly to put your cat's photo as the screen background, and you can use the built-in wallpapers, or make some cool wallpaper with the new zoon features of the camera, and the new zoom effect is extremely smooth, good.

The Third-party Services

In the past, when you created video games on your iPhone, you needed a network to share the points with your friends, or even playing games. Now, you can use the Game Center, which can arrange games, shows the results, and share the points. Unfortunately, many games do not support Game Center services.

iPhone Will be Jailbroken

You can use RedSn0w to jailbreak your iPhone and add some software without Apple's permission, but you can not jailbreak iPhone 4 because RedSn0w has no support for it. (iPhone SDK and iPhone Linkpad recommended)

More Pleasing Appearance

Especially, the folder and new sliding window are the most attractive. Once you compare iPhone OS 4.0 with the iPhone OS 3.x, you will see dramatic changes. In contrast, iPad is just like a primitive who is attempting the OS design.

At last, if you are using iPhone 3GS which has all the features mentioned above, and it is unnecessary to upgrade your firmware to the iPhone 4. (Read more about iPhone 4G VS iPhone 3GS in 8 Features)
