At the risk of being called a "whiner" or being told that my input on a discussion board is "irrelevant," I'll just say that I was talking this over for a few minutes last night with a friend of mine, and both he and I are on 5.11.07, so we're not clamoring for an unlock...in fact, we're both fairly happy with AT&T and don't see anything down the road that would make us want to jump ship to another carrier anyway.
That said: I completely understand what bradl is saying here. Yes, if the Dev Team releases an unlock for 5.12.01 in the next two weeks, say, then there's probably a 50% probability that Apple will have enough time to research and patch it for OS 3.2 and, say, a 95% chance they'd patch it for OS 4.0 (note: all numbers pulled out of posterior but are based on prevailing trends in the market😀)
So, should the Dev Team sit on the exploit and wait for 3.2 or 4.0 before releasing it? Well, what are the chances that Apple, or other embedded systems and software engineers working on baseband firmware (forgive me, I don't know who manuf. the cell radio chip(s)) find the repeatable crash and fix it before 3.2? 25% chance? What about before 4.0? A 50% chance?
I guess another thing to think about is this: what are Deav Team's goals in unlocking cell phones? The nobility of unshackling users from the bonds of their carriers? Sticking it to the big, bad evil carriers/Apple? A mix of both?
1st bottom line is this: if a user chooses to buy an iPhone and can only use it in their location by unlocking it from the official carrier retailer, then it's that user's responsibility to make sure he/she heeds all the advice of the Dev Team and follows the rules of engagement pertaining to their unlock (that is to say: don't update without first checking with the Dev Team!!!).
2nd bottom line: if it's Dev Team's goal to help as many new or would-be users get on the iPhone/unlock train, then they should try to release exploits every chance they get. Problem with this is, though, that Apple has infinitely more resources to throw at patching and closing exploits.
Double-edged sword, I say!😀
(note: I'm relatively new to the jailbreak and unlock sagas, and it's nothing if not entertaining to watch!
