So I just ordered one, and even with 3-day shipping added, it's not supposed to deliver until a week from today. And now that I'm back in the office, I'm back to having no service. So I can expect to mostly have no service for the next week or so, I'm sure.
I suppose I could pop my SIM back into my MDA, but I bet the battery is shot.
Anyway, the moral of the story is, I should have just ordered one online last night. Except if I had, maybe my delivery date would be the 10th, and I have to go to the dentist that day. My plan now is to work from home next Friday so I'll be there when it comes. Fingers are firmly crossed.
