iPhone is tightly controlled by Apple and as with every digital device that restricts usage, iPhone gets hacked too. Each time Apple plugs a loophole Hackers find new ones.
3 Days ago, iPhone superhacker GeoHat (George Hotz) released a new hack to unlock the new baseband of iPhone (05.11.07) by name Blacksnow. He also created Blackrain earlier, the easiest jailbreak available for iPhone, which enables the use of non-apple approved software on iPhone. It hardly takes 30seconds to get rid of the locks (The older methods needed firmware changes, which were time consuming affairs). The one by GeoHat is so simple and brilliant.
Just goes to prove, locking mechanisms are just a nuisance that never really work. While companies may have business reasons to lock phones and restrict usage, it has rarely worked if the product is used by large enough number of people.
A good hacker can reverse engineer and figure a way to overcome such artificial locks. And typically this creates an subsidiary industry which thrives on breaking such locks.
Wonder if there isn’t a better way for business to be conducted than resorting to locks and other such restrictive measures.
