hi,
if i get an iphone 4, i understand you get a new microSIM chip. but say i want to keep my whatever noniphone lying around as a backup for emergencies, will that old SIM card in that old phone still work?
if yes, then does that also mean if i wanted to sell the iphone 4 on ebay, i would be ok? i'm wondering in case we upgrade everyone in the family plan, but not everyone wants an iphone.
