Answer on Is iPhone 4 avaiable in USA without contract AT&T (because I live in Italy) on 24th June? How much it costs?
yes i believe it is . it will be 299 with a 2 year contract from at&t for a 32gb iphone 4g . I am guessing it will be about 600 without a contract because thats how much a 3gs was without a contract when it first came out and they were both the same price with a contract
