vLink Virgin mobile

After reading the posts on the new vLink USB modem for Internet connecti- vity by Virgin mobile, I find that none of the posts indicate the speed that will be supported. I wish to know this and all the other technical details and contact information about this new service purported to have been introduced. I would sincerely appreciate receiving them through my e-mail, the ID of which has been given above.
Thanks.
