Easy Peasy - simply install Tether on your new BB, look up your registration code from your download page on tether.com, and then from "options" on your BB, enter the reg code. it will tell you "Registration code already in use - do you want to assume ownership of it"? Answer "Yes" and instantly, your BB PIN# will be updated in Tether's database. You can verify this by refreshing the download page. This procedure worked flawlessly for me on a VZW Tour when I got a new phone last Friday because the trackball was sticking. I was very impressed at how easy it was to change phones.
