Yeah I see through Apple.com that it only gives me single data plan options, despite being on a mobile share plan.
I hope you are right, because if this plan is lost its gone. Lets hope that when you activate your new device your plan doesn't automatically change over to 10GB for $100 or something.
They keep telling me that they can add the plan back if it's lost but I don't believe them either. I had them note on my account that I want to keep the promotional plan so hopefully activating the phone won't have an effect. If I ever get my phone I'll report back lol!!
