Anysim-1

AnySIM, the free software unlock by the iPhone Dev Wiki crowd, now works with iPhones that are running firmware version 1.1.1. The first version of AnySIM, released for 1.0 versions of the iPhone firmware, didn't unlock the iPhone correctly. So, when folks that unlocked their iPhones with AnySIM updated to 1.1.1, it bricked their iPhones. This version of AnySIM doesn't fix that issue. They claim that this version won't cause the same problems as the earlier versions, but it might be a good idea to hold off on unlocking with AnySIM for a while anyway, caveat emptor. You have been warned. Speaking personally, I went crawling back to iPhoneSimFree to fix the broken AnySIM unlock. But, if all of those warnings are of no use to you, you can get the new version of Anysim here.
