The wife had an iPhone ordered through the att store. As of today it still showed as back ordered so we drove to our local store and she got one on the spot. She qualifies for the upgrade pricing because she is out of her 2 year contract. When we got home she called to cancel the order but they told her it has already shipped out. They told her she could just return the phone to the att store within 30 days without any issues. My question is this... I could "not" get the upgrade price because I got my 3G last July. I won't qualify for upgrade pricing until 3/2010 If I swap out my 3G sim when her other 3GS arrives am I at risk? I know the sim will work but I am unsure if when I actually activate the phone att will pick up on it. Just wondering if it's a risk at all. Both phones have been paid for.
