There is a hardware developer obsession with "unlocking" the Apple iPhone that has spread to the media. The state of being unlocked allows the handset to be used on networks which do not have cellular distribution deals with Apple. In the US, that privilege belongs to AT&T (T). Since some network technology is not compatible with the iPhone, it is not such a big deal as it seems at first.
iPhone unlocking is ready. The unlocking procedure as been cracked, and programmers are currently working on creating customer client software for the procedure.
The first generation of the iphone was already cracked, but now also the new iPhone 3G. So-called “jail break” is necessary to carry out the simlock removal.
Jailbreaking and the method used to hack the iPhone might also change policies for other companies. The RIM BlackBerry App Store, for example, might update their policies by filing a similar statement with the Copyright Office. While unlocking the iPhone is frowned upon by Apple, it might take further action by asking other wireless carriers for cooperation.
Please be very careful when you need your Apple iPhone to be unlocked. There are heaps a of hobbyists, amatures who claims to be “pros” in unlocking phone and quoting unrealistic low price (too good to be true). You might be taking a risk to let the amature “try” or play with your Apple iPhone.
