Google Voice is "one number to rule them all". I’ve known all along that Google would create "clients" for the Blackberry and the iPhone eventually. In the mean time, I wanted to do everything I could to make GV as usable as possible. I tried the free version of GV Mobile for the iPhone (iPod Touch) and liked it so much, I paid for the full version, knowing that at some point, Google would give me something for free. Still, at $2.99, the iPhone app was worth it.

The Blackberry has the GV Dialer app. I gave the 30 day trial a test run and was so underwhelmed, there was no way I would pay $7.99 for the real app. Thankfully, Google saved me.

Google Voice for Blackberry is free and quite usable. It does what it needs to; doesn’t try to do too much, and doesn’t get all wrapped around the axle when it comes to integrating into the Blackberry. My one complaint from initial testing is that it needs to do more caching and reduce the amount of effort and bandwidth it puts into my data connection when what I really want is to place a phone call. It needs a small amount of data to signal the servers for the call but otherwise, it should be less heavy in this department.

One complaint I’ve read but don’t echo is; "you can’t simply open your BlackBerry phonebook and dial via Google Voice". Personally, it was a pain to get my address book sync’d but I had to do that for the iPhone so now it’s a non issue. Besides, Google Voice remembers most recent dialed numbers so more often than not, I am dialing from my history and not from my address book.

So, for now it’s Google’s own app for the Blackberry and GV Mobile for the iPhone. I look forward to comparing Google’s own iPhone app when they launch it.
