ZiPhone is a famous unlocking tool for MacOSX and Windows.

Release notes:

ZiPhone 2.5 is now on download site for
you all to enjoy. I decided to release it for everyone since MANY are helping supporting sponsors. And it would not have been fair to them.

I suggest you to do a restore to 1.1.4 not an update. Because installer keeps old installed apps in it’s cache and you would have problems.Hoping people at nullriver software resolve that soon. After restore to 1.1.4, just use “ziphone -Z Y” or the first button on GUI versions.

Have fun! And thanks to everyone for supporting and caring! Stay tuned! More interesting things are coming up on this site!
