From the phrasing you use, it sounds like you haven't actually tried to activate it - you just took what tech support told you as fact and left it at that. Have you tried activating the phone? Seems like it works fine for plenty of people who follow the instructions in the box or in forums.
After dealing with tech support, I did try plugging in the sim card and turning the device on just to see what would happen. Tech Support told me they activated the Sim card, so I thought I might be able to continue with the included instructions. After 45 minutes the phone was still trying to activate. I powered off.

There do seem to be more people reporting successful activations than problems. However I have noted several users whose problems are nearly identical to mine, and they received similar information from tech support. I suspect the problem is more than a mere failure to follow instructions.
