Question: is siri available on iphone 4?
Answer: iPhone 4 owners can legally get Siri, know-how required. Apple releases an iOS 5.0. 1 update that leaves RAM disks unencrypted, allowing those with technical chops to get Siri running on their iPhone 4s. If you own an iPhone 4 and really want Siri on it, a new update has paved the way for you to get your wish.
