I am really enjoying the Skydeck service on my Blackberry. It basically gives you an inbox for all your phone calls and gives you voice mail transcription that is quite a bit more accurate than Vonage. One of the best features is the way it adds contacts automatically. If I call a restuarant, Skydeck will notice, look the number up in a directory and add the information to my address book. So I can place a call and within a few minutes I have their name, number and address in my phone.
