Apple IPhone 4S

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.


Technical specifications are available at




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

Malware alert iPhone 5 spam emails

October 4th, 2011

Malware alert: ‘iPhone 5’ spam emails


As you may be aware, the new Apple iPhone will be announced today, at Apple’s headquarters in Cupertino, California. At 6pm UK time, the press and special guests will arrive at the “Let’s talk iPhone” event. Finally, Apple will end all the speculation surrounding the upcoming iPhone and reveal it to the world. Is it called iPhone 4S? iPhone 5? Will there be just one model, or two? What will it, or they, look like? All will be revealed this evening.






As is customary on such occasions, hackers are taking advantage of the hype by sending spam emails purporting to be from Apple. The emails contain a link to malware.




The email advertises the ‘iPhone 5’. This should send alarm bells ringing, as it is not known whether the ‘iPhone 5’ will be revealed today, or indeed if it even exists. The emails also contain grammatical errors. The sender may purport to be ‘news@apple.com’, but this could obviously change.



The malware only affects Windows PCs. Clicking on any of the included links will attempt to download the file ‘iphone5.gif.exe’ onto your machine.


Sophos and F-Secure have announced advisories. For more information, visit the following sites:






If you receive this email, do not open it, and delete immediately.



To combat this problem, it is recommended that antivirus products are kept up-to-date, and that an advisory is sent throughout your organisation.

USB 1.0 vs USB 2.0 vs USB 3.0

October 3rd, 2011

Introducing USB3.0
Since around 2005, USB2.0 has been the dominant standard for connecting external devices such as hard disks, tape drives, digital cameras, memory sticks, wireless cards etc. If you have connected any external device to a computer over the last 7 years, the chances are that you will have used USB2.0

Over the last couple of years, USB 3.0 has begun to emerge. Any newly purchased computer will have USB3.0 ports.


The main improvement is transfer speed: USB2.0 has a maximum speed of 480 mbps (megabits per second), whereas USB3.0 is capable of a whopping 5 Gbits/s (5000 mbps), or a 10x speed increase. This means that if it takes an hour to transfer some data to a USB2.0 device, it could take as little as 6 minutes using a USB3.0 device.



As with previous versions, USB3.0 is fully backwards compatible, therefore any USB2.0 device will work when plugged into USB3.0 ports.



Another major advantage is that USB3.0 devices will work with USB2.0 ports, though obviously at a decreased transfer speed. Therefore, it will not be necessary to replace computers, or add an expansion card, just to use these new devices.
