This morning the text message program on my Thunderbolt stopped working. It says "loading" and can't open the message I'm trying to view. It can't open any of the saved message threads I have on my phone. It will let me know when I receive a text and I can click on the app and see the first line of the text but it will not open so I can view the entire message. I have rebooted 3 times and it still isn't working. This a problem with my phone or the network?
