7. After following step 6, your device will be in DFU mode and greenpois0n will start jailbreaking iOS 4.2.6 on Verizon iPhone 4.

8. Once your Verizon iPhone 4 is successfully jailbroken untethered on your iOS 4.2.6 software, then your Verizon iPhone will reboot and you will see a green icon named “Loader” on your device.

9. Tap on the green “Loader” application to open it, and then tap on Cydia and tap on “Install” to install Cydia. Now Cydia should be on your iOS 4.2.6 jailbroken untethered device, and you should be able to install jailbroken apps on it.

Troubleshooting

1. Cydia does not show up on my iOS 4.2.6untethered jailbreak device after using Loader? – Try rebooting your device and seeing if it shows up. I had to restart my iPhone 4 and it showed up after rebooting.
2. greenpois0n is stuck on greenpois0n initialized and has the following error message:
   • • unable to find gBdevList
   • • unable to find fs_mount
   • • unable to find fs_unmount
   • • unable to find fs_load_file
   The above problem did not occur on my device. If anyone had this problem, please be sure to share how you fixed it in the comments so other people can fix this problem if they come across it as well. UPDATE: Greenpois0n RC 5.2 is released, and should fix this problem.
3. greenpois0n RC 5 Beta 4 Quit Unexpectedly – Just relaunch it and try it again!
4. Loader is not installing Cydia – Due to many other users like you, the server which hosts the Cydia download is overloaded. I recommend trying downloading some other time, or you can just use redsn0w 0.9.6 rc8 and install Cydia through that. It’s very easy to use redsn0w and install it and that’s what other people seem to be doing too right now.
