Hi,

I'm upgrading from a 1st gen iPhone and began the activation process with the new SIM in the phone. When I hit the activation wall, and was informed that it could take 48 hours, I figured I might just try my old SIM card. I put the old SIM in the new iPhone and now it works fine - but I'm wondering if sometime within 48 hours, the new SIM will be active and the old one will stop working... Any thoughts?
