Adam of Lifehacker points us to this Voice Dial application for the iPhone, which allows you to record voice samples for any contact on your address book and bring it up just by talking. You can activate voice dialing with the two-press home button trick introduced in iPhone 1.1.1, but you can even put tags on actions like checking your websites, opening email or doing some Google Mapping. Voice dialing is one of the iPhone's missing features we lamented about in the iPhone Book we wrote, but Voice Dial (even if it costs $33) goes a long way to patching it up. Plus, $5 off now for a limited time! [Makayama via Lifehacker]
