Apple has imposed a restriction to edit the Siri query to one time. That means, if Siri doesn’t understand your input query content, you’ have got one and only one chance to make changes to it through your iOS keyboard. But, there could be a possibility where you end up making a typo or Siri doesn’t understand your edited query. In such cases, you’ll either require to input a whole new query or at best install SiriCorrectInfinity cydia tweak.
Developed by rvirajm, SiriCorrectInfinity tweak essentially removes the one-time edit limit and allows you to edit any phrases that you input via Siri assistant as many times as you want to. The tweak comes incredibly handy in situation where Siri sometimes doesn’t understand your query due to microphone interference or because of huge difference in voice accents.
SiriCorrectInfinity cydia tweak can be downloaded from cydia store under ModMyi repo and works on all jailbroken iOS 5.0, 5.0.1 devices installed with Siri (support Spire tweak).
