The iPhone 4S is currently the most powerful mobile phone that Apple has ever made. But it has been criticized by many because it looks very identical to the iPhone 4. However, once you switch it on, you will see that it is completely different. The iPhone 4S uses the latest iOS 5 operating system by Apple. This mobile phone does not need a computer to be activated. The iPhone 4S also includes the iCloud software that allows you to store apps, photos, calendars, and contacts to and from your iPhone 4S mobile phone.
Setting up the iPhone 4S is very easy and will take less than 5 minutes. Because the iPhone 4S uses the same case and design as the iPhone 4, you can simply swap over your SIM card. If you owned a previous version of the iPhone such as the iPhone 4, you might ask yourself why you need the iPhone 4S mobile phone when you can just upgrade your old iPhone's operating system to the new iOS 5 operating system and get almost all the new features.
The new iPhone 4S has a faster A5 dual-core processor that makes everything quicker. The new processor makes web pages load up faster, makes iPhone applications launch quicker, and makes multi-tasking more fluid than before. You will also notice that resource-hungry applications such as the Pages app do not lag anymore when you edit your documents. The iPhone 4S A5 dual-core processor also increases the graphical prowess of this mobile phone. You will notice smoother visuals when playing graphics-heavy games such as Real Racing 2 HD.
The iPhone 4S also has an improved antenna that allows for faster 3G connections and quicker loading of web pages. You will also experience less call dropouts compared to the previous iPhone 4 mobile phone. The iPhone 4S camera is capable of taking 8-megapixel photos and 1080p video. The best feature of the iPhone 4S is obviously Siri - a voice-controlled app that acts as your own personal assistant. You can ask Siri to send a message, dial a number, check the weather, and a lot more. You can even have a conversation with it and you will get some interesting responses. The iPhone 4S mobile phone battery was also improved, resulting in a longer battery life compared to the iPhone 4. All in all, the improvements on the iPhone 4S is enough to warrant a purchase. It is not the iPhone 5, but a faster and better version of the iPhone 4.
