iPhone 4S Siri: Now working on iPhone 4 smoothly?

Siri working on iPhone 4?

 Unnoficial Apple weblog Tuaw is reporting that on Sunday, Apple application programmer Steve Troughton-Smith and application developer for Cydia Grant Paul have successfully ported Siri on the iPhone 4 and the iPod Touch 4th generation. The report adds that Apple’s novelty feature on the two unofficially supported devices is fully functional.

For starters, Siri is an exclusive voice command application for the iPhone 4S, Apple’s new smartphone with dual-core processor and iOS 5 pre-installed. Siri rely on internet connection and Apple’s servers, and the hacked Siri application on the iPhone 4 and 4th generation iPod Touch, according to the report, work the same — it transmits and receives data from Apple servers.

And unlike the previous attempts made by the team, the videos show that Siri on the iPhone 4 run at full speed and connects properly to Apple’s network, but the 4th gen iPod Touch reportedly failed to transmit the voice data to Apple’s cloud due to the device’s microphone, which is reportedly not “as good” as the iPhone 4.

Troughton-Smith told 9to5Mac that Siri on the jailbroken iPhone 4 seems to be fully functional, adding that he’s still working on the “rough edges.” Hit the source links below for the full coverage, and see the developers’ video embedded below.
