Ooh, chalk this rumor up to something we’d be very, very glad to see. A tweet went up yesterday which has since been pulled, saying:
Official word–Windows Phone 7 will support USB tethering, carriers can NOT charge extra, above the data plan.
Correction to #WP7 tethering–that is not official, may not happen. I misunderstood a discussion. Tweet removed. My apologies.
It may or may not happen, but if it does, that would be absolutely amazing. Hardwired tethering that the carrier wouldn’t be allowed to charge for. Verizon and AT&T would probably have kittens if this went through.
