First off, I think you can tether any Android phone to create an Internet connection no matter what computer you have, though the methods differ slightly by type (search for PDANet, Barnacle, EasyTether in the market). Legally and technically, it appears possible. Verizon won't give you support to do it and if you ask for help, Verizon will likely want you to pay an additional $50 a month for some kind of a mobile data plan (yikes!). In terms of xfer cap, I've heard you have up to 5GB per month free on the "unlimited" data plan (yeah. I know. Seems contradictory, right?). After that, it's $0.05 per MB, I believe. That total includes any xfers you make on the phone alone. Not bad, I wouldn't think... I don't see most people hitting huge xfers with the mobile phone and hopefully the tethering is used as a backup, not the norm. As for info from Verizon on this, if found this post on their forums: http://forums.verizon.com/t5/Android-Devices/TOS-limitati...
