I'm attempting to upgrade to the 3G iPhone and after selecting the voice and data plans I want to add 200 text messages/month, but the only options under Text Messaging are to Opt-out or None. Should I just sign up and then call to add text messaging? I'm confused why it wouldn't be there. I'm under the impression I don't get a discount on text messaging, which is fine, but I would like to have it available for $5 like I'm paying now. Any experiences or suggestions? Thanks.
