PREPERATION STEPS - Highly recommended you do these first.
Launch iTunes with iPhone/iPad plugged in and make sure it completes a backup of your device.
When the backup is 100% complete, quit iTunes, unplug your device, replug your device then follow the instructions below.
Doing that first will make for a much quicker process.
Completely new guide for noobs. I just found a way to do it on my iPad 2 [Wifi only] on iOS 5.0.1..
1) Download the file above in step 3, then extract the folder to your Downloads. (Start Menu, your name, then on the left, downloads.)
2) There should now be a folder called: "cinject_0.4.3"
3) Open up CMD and type this (Without "" quotes..): "cd downloads"
4) Then, do: "cd cinject_0.4.3"
5) After so, type this command into cmd.. "cinject.exe -i payloads/jailbreak.mobileconfig"
6) On your device, click on install, and when prompted to type in a password, just click next, with no password in.
7) After so, type this command: "cinject.exe -j payloads"
8) Just wait a little bit. ( Don't freak out, or jizz )
9) Now after a few minutes from step 8, now type this command: "cinject.exe -w"
10) On your device, after doing step 9, toggle the "VPN" switch on in the settings, in about a few seconds after, it should say error.
11) Wait, then it should restart. Cydia is now installed, and your device is now free!
Worked on my iPad 2 5.0.1 fine.
Trying on my 5.0.1 iPhone 4S.
