Why would Apple want to disable these phones?
I can think of a number of reasons, not the least of which is contractual obligations. While I (nor anyone here) is privy to the exact agreement between ATT and Apple, it is not hard to imagine that ATT set certain requirements in the software specifications. Specifically, it is very much in ATT's interests to have this become a brick if not activated.
ATT makes jack on an iPhone sale, and nothing from the majority that were sold at Apple Store. They are not in this partnership for altruistic reasons- they want subscribers, and lots of them. I am sure that insuring use on their network is a KEYSTONE of their side of the Apple/ATT agreement.. it has to be! Otherwise, ATT gets nothing.
Look at the iPhone requirements. It specifically states- in no uncertain terms- that a two year contract with ATT is required... not optional. It is well within Apple/ATT's rights to remotely disable an iPhone, or have a time bomb in the software that, when it cannot verify, will reset the iPhone.
So I am not surprised to see these working today, short term. Check again in November, it may be an entirely different story.
Quite frankly, how much money is Apple making from the calling plans anyway?
OK, let's say they get a cent- one thin penny- from every subscriber month. They are already in the black on iPhone itself. SO here is a new revenue stream that costs them nothing. Best current estimates are 500,000 phones sold over the weekend- that is 5 grand free and clear for nothing. I know that is not all that much for a large corp, but that'll keep Jobs in turtlenecks for a while.
Now we can guess that they make more than 1 cent, and we know the sales will only go up... and it is, in effect, free money, coming in every month for nothing on Apples part. Up that to 10 cents on each monthly 59.99 (which is still just a sliver) and Apple rakes in 50K this month. A buck cut- 500K. Now that IS serious money.
So, reason 2 for Apple locking the phone down- loss of part of this "free" revenue stream. And to discount a free money source- of any amount- is just not done.
Apple doesn't lose anything from people performing these tricks. They still made the money selling the phone, and as I mentioned before, how much money are they making from AT&T through the calling plan?
Apple potentially loses a lot- ""free" cash for one, and could lose much more if it is in material breach of their contract, and there are fines or such imposed. Again, I do NOT know there is such a clause, but ATT would be stupid not to have an enforcement clause. You may not like ATT, but I doubt they are stupid on this count.
ATT joined with Apple on this to make money. And we know the terms are NOT good to the phone company- remember: Verizon turned it down. ATT must have some ace up it's sleeve, some way to insure their money stream, or Jobs would still be shopping this phone.
On the subject at large, I would be willing to bet that this will work for a while... but I also bet that come November, we will see a lot of whiners posting when they see they have a 600.00 brick.
my 2 cents.
