X iPhone: iPhone by the next will be completely close-source

in the last day’s online chase rumors of a possible sale, with the next X iPhone (iPhone perhaps 5) of a SIM card created specifically for the iPhone by and sold in combination with it. This option is realistic? It will make the iPhone by increasingly close-source?

Many detractors of the Apple iPhone and then the same, always critical of the "transparency" of its operating system and then the utter absence of open-source (unlike Android). For several days the tam-tam in the network issued a new announcement: the upcoming Apple iPhone may sell in conjunction with a SIM card for use with the integrated intelligent melatonin. So once you bought the new iPhone future, you should not do is connect to the Apple Store already well known and enable the operator SIM smart choice that best suits your needs. Now the choice is likely to be successful but dangerous. Winning because it would create a device made completely in Cupertino with a SIM card device specifically designed for the apple and introduce services that could not possibly imagine that revolutionary (although on the latter are as skeptical). But look at the downside: the SIM card built probably after buying the iPhone by using Apple Store will need to activate the SIM with the same operator who convinces us more. But here's the Question: What if I wanted to put an existing SIM or a SIM of another operator, what should I do? Would it be possible? The iPhone by this way would not be less open-source, and then become completely "close-source"? I would also expect battles by phone companies that this probably would gain or less to compensate, increase the phone bill with tougher on them (and against Apple) by consumer associations. In short, the possible scenario could be very interesting, but it would be better to first see if the SIM is built just a fantasy or a real possibility.
