The price of an iPhone could rise to around $3,500 if Apple moves its smartphone production to the United States, according to a report by CNN.Moving iPhone production to the U.S. would be extremely expensive, estimated by a tech analyst at Wedbush Securities.Recreating Apple's efficient supply chain in the U.S. would be challenging and costly, requiring at least three years and around $30 billion.Higher labor costs in the U.S. and additional expenses would likely result in passing on the extra costs to consumers.
