I just got this phone today, and I'm trying to set up my email.
I got one account with an @yahoo.com address working fine, but when I try to get it to register my @rocketmail.com address it keeps telling me that my username or password are wrong, and neither are entered wrong.
It will not log into that account for some reason, and that is my business email. The @rocketmail.com one is an offshoot of yahoo. It is an address that you can select if you wish your e-mail to not end in @yahoo.com.
