iPhone Unlock Toolkit
There are many iPhone owners who have their device locked by a specific provider so that the phone cannot be used with other networks. Unlocking the iPhone might be a partial solution because initializing calls using a different provider may not work. However, the device has many more uses that will become available through that procedure.
In case you are in dire need of unlocking yours, you should note that this procedure may cause some damage, especially if inappropriate tools are used. To avoid this, you should always check the accompanying documentation or look for references insofar as such software is concerned.
One of the utilities that claims to render your device usable outside some restrictions imposed by the service provider is iPhone Unlock Toolkit. The program is very easy to use, as you will surely notice when meeting the extremely simple interface.
There are only two buttons available: one for starting the unlocking procedure and the other for closing the application. There are no configurations to be done and everything should be as easy as one click can be.
If the procedure is successful, you will be able to use your iPhone as a music player, for example,or, if the wireless connectivity is activated, as a personal digital assistant or PDA in short.
Since it is reported that the program only works with a specific version of iTunes and supports only a few iPhone firmware releases, it's best that you check this prior to using iPhone Unlock Toolkit.
To sum things up, the software definitely has some potential, but, at this point, it's only a matter of chance if it will actually work for your device. It may be very easy to use with its single click operation, but, just to be safe, you should make sure everything is backed up before proceeding.
