JDB I had my phone optimized recently and had to change my MFN password. MFN reset my password and I'm able to log in on the computer, the problem is that I can't log in on my phone. The message says username and password combination is not valid. But I can log in on the computer but not the mobile phone.
Are you sure you are using the right password on the phone? There shouldn't be anything fundamentally different about the login process between one and the other.
