I'll be switching from an iPhone 4. I've been waiting on Windows Phones to be shipped with front facing cameras so it looks like I'll be going with the Titan since I'm on AT&T. Can anyone tell me if you can choose certain contacts that will always go to voicemail when they call like you can in Android? It's not a deal breaker but I'd really like to have this feature. If not is there a call/text blocker of any kind?
