Edge & 3G Not Working on iPhone 4 After iOS 5 Jailbreak & Unlock

Hello to all, I am new here, and have recently jailbroken and unlocked my iPhone 4 on iOS 5 using Redsn0w and Gevey SIM. But after doing so, Edge and 3G service is not working on my iPhone. Though I can make and receive calls. So what do I need to do? Thanks.

Hello Nate! First, I would recommend you to reset your network settings. Just navigate to Settings -> Reset -> Reset Network Settings (please note that this will delete all your network and network password). Also, have you managed to hacktivate your jailbroken iPhone 4 after jailbreaking it? Do you have the original SIM card of the carrier to which your iPhone is locked to? If yes, then simply pop it into your iPhone, connect it to iTunes, and then follow the onscreen instructions in order to activate your iPhone.

Alternatively, if you don’t have access to any official carrier SIM card, then you can download and install SAM app from Cydia Store. If you need help in installing SAM, then you can follow our step-by-step guide posted here on how to activate iPhone using SAM. Then after activating, tethered boot your iPhone and then check your device. You can also download and install Ultrasn0w 1.2.4 to fix your network issue. However, you will need to tethered boot your iPhone using Redsn0w in order to activate Ultrasn0w unlock. That’s it! Good luck...
