I read the article about the iPhone..I stopped useing a Cell Phone when I started useing PCs..and in that practice regualrily check my PORTS..

The technique of gaining access in the Travels of your Cell Phone inter-act in the Un-Locking method..and offers you to OPEN Port-22.and use a Wi-Fi network..

Those two ITEMS sound risky to me as a Persoanl Desktop User..and then the mention of only useing a MAC would somehow just be asking for trouble..

I would not Un-Lock a iPhone should I ever Pay-$$400.00 to talk on the phone..

I see deals all over the place that start at $$39.00 and approach $$99.00 w/contact deals..plus the use of Calling Cards might need to be expanded to include some World Travel..

Un-Locking an iPhone sounds risky and even foolish considering you shelled out $$400.00.
