I already have a ST plan ($45) that has been activated for a ST LG phone. I want to switch it over to an Iphone 3 that I got from my son. However, when I put the sim card into the Iphone it tells me "emergency calls only". When I hook it up to itunes, it tells me "I'm sorry, we are unable to continue with your activation at this time". I already have an existing Itunes account that was previously used with another number that I no longer have.
What do I need to do to get the iphone working on my current ST plan?
Thanks
