How to Fix FaceTime on iPhone 4 After Redsn0w Jailbreak?

Hello Lilleth, since your iOS device was jailbroken and hacktivated using Redsn0w, you will need to activate it in order to be able to use all of the features on the jailbroken iPhone. The activation process to iTunes is pretty simple, all you need to do is simply connect your iPhone to your Mac OS X or PC via USB cable, and then upon connection iTunes will launch and automatically guide through the entire activation process. Well, aside from iTunes, you can also activate your iPhone using an app that can be downloaded from Cydia Store called SAM. This app is beneficial for users rocking a jailbroken and unlocked iPhone and don’t have the official SIM card to activate their beloved device. For those of you who aren’t aware, SAM tricks iTunes to generate legitimate activation packets for your iPhone which in turn fully activates your iPhone. Anyway, if you want to try SAM then you can check out this tutorial on how to activate iPhone using SAM.

On the other hand, we don’t recommend to our readers to restore their jailbroken iOS devices to the latest firmware, especially to those who don’t have save SHSH blobs which was created using Cydia, iFaith, or TinyUmbrella. In your case, I would recommend you to save your SHSH blobs using iFaith SHSH Blobs Dumper so that you will be able to downgrade your iPhone back to iOS 4.3.3 if you have accidentally restored your iPhone to iTunes.
