A short video showcasing Apple’s new iPhone 4S surfaced on Monday, and now we have our first full “YouTube review” of a handset that was seemingly delivered ahead of schedule. YouTube user applemastertouch has posted a video walk-through that is nearly 9 minutes long. In it, he shows off Apple’s brand new smartphone and gives us a thorough look at the device’s most highly anticipated new feature, Siri. Other iOS 5 features make appearances as well, but Siri is the clear star of the show as we see various commends that can — and cannot — be acted on by Apple’s new personal assistant feature. While over a million consumers anxiously await delivery of their iPhone 4S handsets, hit the break for a taste of things to come.
