I'm not sure if this is as big an issue as "Alpha's" and this poster's wording makes it seem. You can tell by his sometimes subtle use of hyperbole that he is clearly an expert at the english language, and from what I can tell he uses it to instill a subconscious sense of overbearing authority and powerlessness. Lots of companies collect information like this, Google collects your IP address and location, if possible, every time you visit a page on google.com. A lot of the time the information is completely anonymous, like it is with Google, and there is no legal way to trace it back to the original person. I could understand why apple might want to collect information about how many people are using FaceTime, and at what demographics, locations, et cetera. Our "Alpha" never said whether the data is anonymous or not, although his wording seemed to suggest 'not.' Even so it comes down to how the use the information. I don't imagine they would ever share or sell the information, and I hardly imagine they would even care about it, on the person-to-person level. They would probably keep it locked up in their servers labled "Company Secrets" or whatever, so that they could then use the general information in advertisements, or as "material evidence" when pitching to companies like Cisco to implant FaceTime capabilities in their own products.
About the OTA carrier updates, these are, of course, confirmed by our first commenter. In the past Carrier Updates have done, well, nothing. It's possible that these carrier updates may, or may not, be more detrimental to Jailbreakers and unlockers, but unfortunately, you signed a contract to AT&T when you bought your phones, and saved $400 for doing so, that gives them the right to do this (read it if you don't believe me, some of it is shocking). If you bought your iPhone unlocked from Apple they are obviously not going to push mandatory carrier settings updates from AT&T, especially if you are not using AT&T. For those of you who really care, expert iPhone programmers like GeoHot or the Dev Team should have no trouble firewalling the incoming Carrier Updates, should they prove to be detrimental. If Apple and AT&T can't contact the phone, they can't lock it.
As for the jailbreak support for AppleCare customers, I am not well enough informed to tell you otherwise. In the Apple EULA that you agree to before using your iPhone, it states that any sort of unauthorized modifications, hardware or otherwise void iPhone warranty, and under the warranty section it says that only warrantable or warranteed products are eligible for AppleCare customer support, which includes Genius Bars and telephone support. If you do a fresh restore of the iPhone Apple cannot tell if you have jailbroken it or not, so you can still get your warranty. As for the other times, just don't call Apple if you don't want your phone blacklisted. The only thing that concerns me here is the blacklisting part. It seems that legally Apple has the right to refuse service to you if you jailbreak your phone, but their jurisdiction should stop there, if you ask me. I'm not sure what hidden clause of the National Vetrans Day Proclamation allows them the right to brick a phone that the user payed for, even if under contract. I guess we'll see how it all plays out, I just don't think it is going to be as big a deal as it's been made out to be.
Besides, MuscleNerd has our backs.
