Voice Dialing Works Using iPhone 4 with Jabra Cruiser Bluetooth Car Speakerphone

I actually don’t make many voice calls using my cell phone (or landlines for that matter). However, it is critical that I be able to voice dial over a Bluetooth speaker in my car for those few times I want to make a call. Until this past spring, the only phone that let me do that was the Windows Mobile 6.1 based HTC Touch Pro2.
This changed with the Android OS 2.2 (Froyo) update for my Nexus One. It finally let me me voice dial using a Bluetooth device:

The iPhone 3GS probably could voice dial over Bluetooth in that timeframe. However, I didn’t have a 3GS, I had (and still have) a 3G which could not voice dial using my Jabra Cruiser Bluetooth speakerphone.
I finally got around to pairing my iPhone 4 with the Jabra Cruiser and am happy to report that my iPhone 4 can voice dial using a Bluetooth device too. I found it interesting that the iPhone 4 and HTC Touch Pro2 both use a simple “ding” sound to indicate that I should say who to call. The Jabra Cruiser says “speak now” to indicate it is ready for me to voice dial when using the Nexus One.
