There are a lot of reasons to hack your iPhone or iPod touch.
There’s this myth that hacking will go away “once Apple adds that one killer feature.” But it’s
unlikely, because the iPhone is unlike the earlier iPods or any phone on the market before it. It is a
full-featured personal computer.

The iPhone is a global device that uses the international standard GSM protocol. Unlocking the
phone so that it can use SI M cards anywhere is a major industry, and will probably continue to be
so even after Apple’s exclusive contracts with mobile carriers are gone.
The iPod touch is the heir apparent of the iPod, and once flash memory sizes surpass hard drives,
the iPod touch will be the iPod. But this iPod surfs the Web, gets email, and maps your location,
and new applications are constantly being developed for it. The impulse to get the iPod—already
the de facto standard MP3 player—to do even more is irresistible.
