Windows Phone 7 USB Tethering

Many stories regarding Windows Phone 7 seem to be of the good news/bad news variety, such as one from MobileCrunch that says Windows Phone 7 will support USB tethering. The really good news part is the possibility that Windows Phone 7 will support USB tethering at no additional telecommunications costs. If true, this means that you can use a phone that runs Windows Phone 7 as a wireless modem for a computer at no additional cost above what you pay for smartphone data service from your wireless provider. MobileCrunch bases the news on a post on Twitter by a person not working for Microsoft who attended a Microsoft event.
