I do see a open network repair ticket for EVDO data in that area. I do not see any closed service tickets for service outage for the time and date you posted. I am assuming since you did place a end time in your original message that you have had service restored.
For what it is worth - I am getting txt/email and phone now on both my work blackberry and personal samsung 3g. I understand from others in the same area there have been some intermittent service outages this week. I was only able to send/receive 1 text between those 7 hours on my samsung, and sent 2 outbounds on my bberry, and show another 20+ outbound calls/txts that were not sent.
Here's another for what it's worth. Yesterday afternoon in 75069, McKinney, my phone just stopped working, not the actual phone, all services. I used Sprint Chat and they "upgraded" something and told me to take battery out, put back in, wait 30 mins. all of which I did to no avail, I just kept getting Error 2048, "network busy". I posted here but no one ever replied. Some time late last night it (services) began again. Today it seems to be working ok.
