This is a 100% fake. I am a graphic designer, and these images are simply smashed together from the cingular site. Also to the person who said it seems odd they are only offering 200 email messages, reread. It says 200 messages, refering to text messages. Cingular has never limited the amount of emails, since it says unlimited internet, you could go to gmail mobile and access as many as you wanted anyway.
Over all point being however this is completely fake, and not sure who made the update saying it looks like its real. After all the fake iPhone pictures, you would think people would have a better eye.
