So I'm purchasing a brand new iPhone 3GS 32GB. I have an extra spot open on my FamilyPlan to do so but need some answers. I'm actually ordering online and receiving in the mail obviously but my plan was to swap the SIM card in the new iPhone already with my current SIM card in my crap flip phone (was once used with iphone so still has 3G plan on it). Is there a penalty or some kind of way of Apple/AT&T knowing if I don't activate that iPhone with the SIM card it comes with? Because my plan was too take the SIM card it comes with and just put in the crappy flip phone..just swapping sims is all, sorry if this sounds confusing. Thank you in advance!
