1. Same design as iPhone 4

Many people expected that new iPhone would be slimmer and more beautiful. The design of iPhone 4S is as same as that of iPhone 4.

One of imagine designs of new iPhone.

2. No bigger screen

We expect that the new phone has a bigger screen to compete with other Android smartphones. iPhone 4S also has 3.5” screen, not 4” as expected.

 

3. No 4G connection

It’s quite disappointed that iPhone 4S doesn’t support 4G. However, iPhone 4S is now compatible with both HSPA+ and CDMA2000.

 

4. Battery is not improved a lot

No information about the battery is now available. Since this smartphone uses dual-core processor and dual-core graphics processor, the battery should be much better. Apple said that the battery of this new phone was improved but we guess that the difference is not much.

 

5. No NFC technology

Whereas the Google electric wallet has been released, NFC (Near Field Communication) technology is still not available on iPhone 4S.

 

6. Not integrated with Facebook

Nothing related to Facebook. Only Twitter is integrated into iOS 5.

 

7. And many more…

People expect much more from the “Let’s talk iPhone” event.
