This continuing cat and mouse game reminds me of radar detectors. I recall when radar detectors first came out, and something akin to an arms race broke out between authorities and lead-footed civilians to stay one step ahead of each other. I'm fairly certain that's a race that won't end until modern transportation takes some strange turn. So it is with the iPhone unlock strategies, and according to iPhone Dev Team vet Nate True the 1.1.3 firmware update will once again break unlocks and third-party applications. The full post offers some fairly convincing reasons to believe that they've got the real scoop. I'm buying it.
Want to put a happy spin on this? Just be thankful that Apple doesn't allow the iPhone-hacking geniuses much idle time, lest some of them find other ways of showing their talent.
