How to Fix Gevey SIM Caller ID Bug on iPhone 4?

Hello Jaxov, fist, just want to thank you for the tutorial on how to use Gevey PRO to unlock iPhone 4. It works perfectly on my iPhone. Anyway, just like what I’ve said, I have a jailbroken iPhone 4 on iOS 4.3.3 and it is currently unlock with Gevey PRO. However, for some unknown reason the caller ID feature of my iPhone got disabled. The name of the caller is not being displayed even they are listed on my contact list. How can I fix this? Please advice. Thanks in advance.

Hello Samuel, you are very much welcome! Any way, we have never experienced this Caller ID bug before. However, some of our reader has reported this to us. After hours of research and tweaking, we have found that this unusual error can be fixed in an instant. There are two ways to resolve this issue, the first method is for non-jailbreakers and the other one is for users rocking a jailbroken iPhone.

So to fix the Caller ID bug, if you are a non-jailbreaker, then all you need to do is to add ‘+‘ then followed by your country code to every number stored on your mobile phone. For instance, if you are living in UK then you will need to add +44, or if you are from India you will need to add +91, etc, etc, etc… Yes, I know, adding country code for every contact in your contact list is a lot of work, especially if you have more than 100 contacts store on your phone.

For iPhone users who jailbreak their device before they unlock it using Gevey PRO hardware unlock, fixing Caller ID bug is a lot easier. All you have to do is download a jailbreak app in Cydia called Caller ID Format Fix and installed it on your iPhone 4 or iPhone 3GS and you are good to go. Caller ID Format Fix can be downloaded under BigBoss Repository for free of cost. Hope this help!

You dont need to install "Caller ID Format Fix" or add ‘+‘ in order to fix this bug, all you have to do is launch Setting and navigate to General -> International -> Region Format -> Select your country.
