Apparently the rumors about HTC HD7 being sold out were true. TMo News posted it on the back-order notification on their website.
This is good news for the WP 7 showing some definite in the phone. The fact it sold out on T-Mobile, the third most popular carrier in the U.S. shows people definitely want the phone regardless the carrier, or that T-Mobile didn’t order nearly enough phones but let’s go with the first.
AT&T said they lines at several of their stores around the U.S. and that they encouraged by the early demand.
Just from early sales and comments it looks like WP7 will be invading the Smartphone Market in a strong way.
