When Apple unveiled the iPhone 4S
on October 4, Siri was seen as the new iDevice’s biggest selling point and a major carrot to encourage iPhone 4
owners to upgrade. Although Siri originally appeared in the App Store in early 2010 before being acquired by Apple, the assumption was that the new version integrated into iOS 5 relied on the faster processor found in the iPhone 4S for Siri to work her voice recognition magic. Developer Steven Troughton-Smith and Grant Paul have proven that is not the case by not only getting Siri working on an iPhone 4, but also an iPod touch 4G.
With around two trillion text messages sent in America alone every year, SMS text messaging is the most widely used data application in the world and the number two use of mobile phones - the first being to check the time. It's also a cash cow for telecommunications companies with the average charge worldwide of around US$0.10 per message for data that essentially costs the telco nothing to transmit because it is sent on the control channel - a small part of radio bandwidth that is used to send information between the tower and phone about call setups. Apple's iOS 5 update - if you can get it installed
- sees the addition of a new iMessage app that could have telcos nervous as it allows text messages to be sent for next to nothing.
