According to reports, iPhone 3.0 firmware may just deliver native voice activation along with voice enabled services says cultofmac.

Apparently this new service, codenamed Jibbler, is an enhancement to the Apple iPhone’s springboard app, a Finder type application which acts as a launcher and supports 3.0 Spotlight search.

It is not known whether these voice services will come with the reported new Apple iPhone hardware or if the features will be compatible with existing iPhones. However the addition of said voice apps can only keep the Apple iPhone on top of the smartphone arena.
