As promised in iPhone Software License Agreement, Apple tracking iPhone usage data
Monday, November 19, 2007 - 02:36 PM EST"Put on your tinfoil hats, because according to the findings of XianLi, one of the members of Hackint0sh, the iPhone spies on you," Jesus Diaz reports for Gizmodo.
The evidence in the code shows that the Stocks and Weather applications send your IMEI number—the unique number that identifies your iPhone and is tied to your personal information—to Apple, along with the nature of the information you are looking at:

"While there's no evidence that Apple actually uses this information for any purpose, good or evil, the code shows that every time you try to access detailed information on whatever stock, your IMEI will be sent embedded in the URL. This could be cross-referenced with IP location and the information in Apple or its partner's databases to gather extremely valuable data for marketing purposes," Diaz reports.

MacDailyNews Note: Apple's iPhone Software License Agreement states, "You agree that Apple and its subsidiaries may collect and use technical and related information, including but not limited to technical information about your iPhone, computer, system and application software, and peripherals, that is gathered periodically to facilitate the provision of software updates, product support and other services to you (if any) related to the iPhone Software, and to verify compliance with the terms of this License. Apple may use this information, as long as it is in a form that does not personally identify you, to improve our products or to provide services or technologies to you."


Odd.
While I don't fear this particular information being recorded, I fear that it is being done all together. I would advise Apple to put a stop to it immediately.
The iPhone has suffered entire too much "Big Brother" control from the start with Apple telling customers what they can and cannot do with the instrument THEY purchased.
Now we find that in addition to their oppressive and stringent controls on usage they are actually WATCHING your actions and delivering PERSONAL data to advertisers.
I've said it before and I'll say it again. This is not the Apple I've supported for years. Some wrong minded people are making decisions in Cupertino these days.
