How To Set Up Picture Mail?

[Drumrintheline]

I have tried many times, both on my own and with a rep, to set up my picture mail service. I have gone through hundreds of picture mail code/passwords you receive via text message on the picture mail website. The problem is that my phone always gets an error. The error says that it has failed to register the device. I'm not sure that I have even been able to receive pictures on my diamond ever since I got it last year. Can someone please help or lead me in the right direction to getting this thing to friggin work.

Thanks in advance.
