I was eager to pick one up as soon as they became available as my signal at home is very weak. That was two days ago and it's still trying to acquire a signal and set itself up. I called and spoke to two or three people in support and it wasn't until I finally got the explanation form one of their upper tier support guys that T-Mobile just can't keep up with the demand for registering all the new devices that everyone picked up. On the one hand, I'm relieved the cell spot isn't defective and I'm not all that concerned about having to wait for it to start working. On the other hand, it would have saved a few phone calls if T-Mobile just sent out that info to their lower tier people who never mentioned the problem.
