I followed these steps:
STEP 1: Download CLI Absinthe for Windows and Mac OS X from the link above.
STEP 2: Unzip the folder named cinject_0.4.3 into the system folder, i.e. C:\.
STEP 3: Now go to the start menu, click on run and type in cmd.exe.
STEP 4: In the command window, type: CD C:\cinject_0.4.3 as shown to get into the required folder.
STEP 5: You’ll now need to execute CLI. Do this by typing: cinject.exe -i payloads/jailbreak.mobileconfig. Tap the install button that appears on your iPhone, there is no password for the VPN so just hit next.
STEP 6: Now type "cinject.exe -j payloads" then hit enter and wait for the backup. (If you get the FATAL(_LINE_) error, go to Settings > General > Reset > Erase All Content And Settings. When you're iPhone restarts, start as a new iPhone and repeat steps 1-6.)
STEP 7: Type "cinject.exe -w" then hit enter. After the first wave of text goes through on the command prompt, on your iPhone, go to Settings - General - Network - VPN and turn the VPN toggle from off to on, after a few moments there will be an error message and the phone will restart, when it starts again, you'll find cydia on the second page of apps.
Everything works, but the vpn never connects. When I restart, no Cydia.
