Since this morning, I've apparently been unable to send/receive messages. I keep getting an error message that says "unable to connect to the internet. You may send and receive messages on your phone but it may be temporarily out of sync with other devices. The integrated messaging service will reconnect once the internet connection is restored. To manually reconnect tap Retry". When I tap retry, nothing happens. Even weirder is that I can receive emails and make/receive phone calls.
