iPhone 4S review

Messaging on the iPhone 4S has been given something of a boost by the inclusion of the iMessage, which is a BBM-a-like service for iOS devices. It can be used on any device running iOS 5, which means conversations can be easily carried across on loads of Apple products without an issue.

While many will expect iMessage to be a separate app in the same manner as BBM, it simply jumps in when a relevant phone is on the other end of the conversation, meaning essentially free text messaging and cool features like read receipts and being able to see when the other person is typing.

However, this will be more useful for iPhone 3GS and 4 models, as it's surely only good to replace text messaging for those that need to save money and haven't got a price plan that offers thousands of messages for free each month.

Email

iPhones have always been looked at as decent messaging devices, and that's certainly true when it comes to email. There's a unified inbox for all your accounts, with multiple email addresses supported on the phone.

Setting these up is as simple as you'd imagine, with only an address and password needed in most situations. As we mentioned earlier, it's so easy to keep track of your emails thanks to the new notifications system, but it's hardly anything new, so not really a unique selling point.

The keyboard is another great selling point from Apple for its iPhone - some people have complained that it's a bit hit and miss in the past, but most people should have become trained in the art of tapping out a message on a touchscreen, so most will quickly be up to speed with the well-known keyboard.

There's a new addition to the keyboard, and that's an option to speak out the message reply using Siri. It's almost unerring in its accuracy compared to other voice recognition systems, although you do need to say things like 'comma' or 'exclamation mark' to add in the punctuation.

We sent 100 messages using Siri to see the accuracy, and found that the accuracy was around 45%, although shorter messages were obviously better.

However, we were relieved to be able to head back to tapping out our messages on the keyboard, as you could make sure what you wrote was correct first go. If you're going to speak your messages, why not just call the person?
