ZiPhone will make intrinsic changes to your phone by using the process known as "jailbreaking". Jailbreaking means that you can go around your phone's operating system limitations and use your phone for applications which the phone has been denied access to. Sometimes there are legal reasons why a particular operating system will not let you use certain applications, but other times your inability to access these applications are for arbitrary reasons, often so that you will only use the technology which the manufacturer wants you to use. This is one of the big arguments between fans of Android phones and those of Apple products, as the former has more accessibility, especially to open source software.
