iPhone 4S: is it worth the upgrade for your business?



The iPhone 4S was announced yesterday, after the usual build-up of speculation and hype surrounding the release of a new Apple device.





Analysts and journalists have been disappointed by the technical specifications of the device, as they were expecting more.




The iPhone 4S will be available from all the major UK networks on 14th October. Pricing has yet to be announced.


So, if you are an existing Apple customer, is it worth the upgrade? Will the iPhone 4S improve productivity and functionality?


What has improved?

1. Faster processor, the Dual-Core ARM A5 which debuted on the iPad2. Substantially faster than the Single-core processor of the iPhone 4.


2. Dual, improved 3.5g mobile antennas. Apple states that it has made substantial improvements to ensure that mobile reception issues are a thing of the past.

The Dual 3.5g antennas also allow one to receive data and the other to transmit, theoretically doubling data transfer speeds over 3g mobile networks, up to 14.4 Mbps.


3. Siri. Advanced voice recognition. Integrated into the phone and throughout Apple and third-party applications, it reportedly works fairly well. Only available on the iPhone 4S.


4. Improved Camera. 8 Megapixels as opposed to 5 Megapixels on the iPhone 4, 1080p Video Recording as opposed to 720p, with facial recognition, advanced backlight and improved CMOS sensor.


What has not improved?

1. Screen. Same 3.5-inch size and resolution.


2. Appearance, dimensions and weight are almost exactly the same as the iPhone 4.

What about iOS 5? Do I need an iPhone 4S to run it?

No. The iPhone 4S will include the latest operating system, iOS 5, upon launch. However, iOS5 will also be available for the iPhone 4, iPhone 3GS, iPad and iPad 2.

One of the major new features of this operating system is iCloud
