Get geeksnow latest version for jailbreak iOS 7.1 - 7.1.1 iPhone 4
The latest version of geeksn0w is 2.9. This is a semi untethered jailbreak which works only with iPhone 4. Semi untethered jailbreaks are not much comfortable like untethered jailbreaks. Cydia will be disappear when you reboot your iPhone and you must have a tethered boot using initial jailbreak tool (geeksnow) to get the Cydia icon back at home screen. Currently this is the only jailbreak available for iOS 7.1 - 7.1.1. MAC version is still in beta but you can run it at CLI (command line interface) if you don't have a windows PC.
