“Developer Steven Troughton-Smith has been working with 9to5Mac exclusively to port the iPhone 4S Siri voice command system to the iPhone 4,” Mark Gurman reports for 9to5Mac.
“Troughton-Smith was able to get the beginning steps of a full port rolling after installing the iPhone 4S Siri and Springboard files onto an iPhone 4,” Gurman reports. “As you can see in the video [below], Siri’s interface loads up with all the features from the iPhone 4S implementation.”
Gurman reports, “You may notice Siri and the iPhone 4 acting very sluggish in the above video. The issue here is not Siri, but is that a special GPU driver for iPhone 4 is needed; and it is obviously not included in the iPhone 4S binary cache – where the Siri files are located.”
Gurman reports, “We are not entirely sure why Apple is making Siri an iPhone 4S exclusive but it could be due to special microphone support, or because the A5 may allow it to run slightly quicker… We are, of course, working with Troughton-Smith to improve the Siri iPhone 4 port.”
