Has anyone turned on their Droid x and the green voicemail icon pops up and it says "Voicemail Activities Received. Data Service N/A Select to Refresh". I select it and it takes me to the visual voicemail screen. But I don't have any new voicemails. When this happens my phone is locked up. I have to take the battery out and put it back in. I haven't downloaded any new apps. Thoughts?
