iPhone 3GS, iPod Touch 3G, iPad, iPhone 4, iPod Touch 4G
4.0-4.1 and beyond+++
limera1n is unpatchable
untethered thanks to jailbreakme star comex
released today to get chronicdev to do the right thing
brought to you by geohot
Mac and Linux coming soon
follow the instructions in the box, sadly limera1n isn't one click
that's the price of unpatchability
as usual, donations appreciated but not required
still in beta, pardon my ragged edges
AppleTV is technically supported, but theres no apps yet
zero pictures of my face

known bugs
3GS new bootrom is broken, fix pending
some people need to restart to get the Cydia icon to show up after installing
some people still don't have windows
beta iOS versions aren't supported
uninstall in limera1n app doesn't work, you can just delete the blackra1n.app directory, i need regression testing
