Is this the correct link for Sprint BIS?
BlackBerry Internet Service
With so many scam websites out there, I'm afraid I to enter critical personal data like my Device PIN & ESN on a bogus site.
I'm also confused, because I already created a username & password on my BB when I set up my gmail account, but now when I try to log in at with at this website, it says "Please check your information and try again". Do I need to register as a new user on the Sprint website again?
