Apple's new iPhone - iPhone 4S, adopts Apple's own dual-core A5 processor, also upgrade video and graphics performance. The most revolutionary feature is the voice control function Siri.you can dial by voice, answer a call, send text messages, set the alarm, open the video and radio and so on. Siri have made iPhone 4S a real "personal assistant". By making dialogue with your iPhone through Siri function, you can easily find restaurants, check the weather or manage your schedule etc.

We have got many users' feedback for iPone 4S Siri function. Some users said, Siri is the best alarm clock, when you are tired and need some rest, just tell Siri "wake me up 40 minutes later". Using Siri to found cafe shops or restaurant can be the most practical function. If you are a travelers, Siri can be the best GPS for you, just inform Siri where you are going to, he will use google map searching and tell the way. Checking the weather? Tell Sir, he will response with the exact info. Sending message is dangerous while driving? Ok, let Siri help you. Tell Siri " Tell my wife, I will be back home later". Siri will send message for you. Wow!

Although iPhone 4S have so many strong functions, but there are still some problems like battery issue. While the more functions you use, the faster the battery will run out. In this circumstance, you'd better get a portable charger with you to supply emergency power while you need.
