Wow, that's a great accomplishment HikingStick, thanks! Be sure to let us know when they get back to you.
I think you're right with the announcement, and I will make an announcement post and move all the T-Mobile discussion in there. Users will see it in their news feeds afterwards.
Even better--I just got a call back from a tech, and he said it is fixed. I tried it myself (disabled Wi-Fi, and used their network), and IT WORKS!!!
