went in today to try to see if they will let me do the challenge with nokia n82 and they did. of course I lost but they didn't have the HTC Radar in stock so they took my number and said will call me when they get the next shipment and all I have to do is go in and exchange it. Hopefully they will honor it and actually call but just in case I will be calling them every 2 day or so to see if they get the shipment.
It seems like the HTC windows phones are the first to go. When I went to my local Microsoft store (va) they were also out of the HTC Radar. But it they didn't offer to call when they got some more in. I just took the nokia 710. Btw.. I used the nokia neuron.
