Hello, I’ve been wondering if I could fix my jailbroken iPhone 4. My iPhone 4 is running on a jailbroken iOS 4.3.1 using PwnageTool 4.3 with Ultrasn0w carrier unlock installed. I’ve been using this iPhone 4 for months now and for some reason I have an annoying problem. I have a very low cellular signal. I jailbroke and unlock my iPhone 4 as instructed and it is activated, but I’m still having issues on my cellular signal. I don’t want to re-jailbreak and re-unlock my iPhone again on new iOS 4.3.3 because I might the ability to unlock my iPhone again. Please help.

To fix “One Signal Bar” issue, just simply download and install Ultrasn0w 1.2.1 on your iPhone. For those who aren’t aware on how to install Ultran0w 1.2.1, all you have to do is launch Cydia app from the Springboard of your jailbroken iPhone. Now, tap on the Manage tab and on Sources section, then on Edit and Add button. Now you have to add http://repo666.ultrasn0w.com as Cydia/APT URL and click on Add Source button. Once verified and updated, tap on Return to Cydia button at the bottom. Click on the Search tab at the bottom and type Ultrasn0w in the search field. From the result, select Ultrasn0w and install. Check your signal bar once you have downloaded and installed Ultrasn0w, if you still got “One Signal Bar” then click on Restart Springboard button or just simply reboot your iPhone.
