To me the iPhone is just like a computer but only able to make phone calls. The ports are block to prevent hackers from using it to hack. But hackers are not silly, as they use the Top Ports. There is a case of a china guy who use a iPhone to hack a bank and apple had to "bribe" the bank so as the iPhone repeutation will not be diminish. Now I think it is I impossible to use it to hack. I hope so...
