Hi Jaxov, I have followed your tutorial to unlock iPhone 4 on iOS 5 after jailbreaking it using iOS 5 custom IPSW which was created using Redsn0w. But, after unlocking and jailbreaking, I have noticed that my cellular signal depleted drastically. I never get a full bar. Is this normal? Thanks.

Step 1: Launch Cydia app on the SpringBoard of your jailbroken iPhone.
Step 2: Once loaded, tap on the Manage tab at the bottom of Cydia followed by a tap on Sources section to view your current Cydia repos. If you see Ultrasn0w’s repo666.ultrasn0w.com repo already added in your current sources list, jump to step 4 otherwise continue to the next step.
Step 3: Now you have to add Ultrasn0w repo. Just tap on the Edit button followed by a tap on Add button. Then enter http://repo666.ultrasn0w.com as Cydia/APT URL and hit Add Source button.
Step 4: Once done, tap the Search tab and enter Ultrasn0w in the search field and search for it.
Step 5: From the search results, select Ultrasn0w (1.2.4) and install it by tapping on the Install button.
Step 6: Cydia will now install Ultrasn0w 1.2.4 on your jailbroken iPhone. Once completely installed, just simply reboot your device to fully activate the application as well as fix your issue.
