How to update my iPhone 3GS without its carrier being lost?
I've learned from my friends that if you update your phone on the latest software, the signal will be lost, the carrier, for ex., Globe, Smart. Is it true? I badly want to update my iPhone 3GS without its carrier being lost. Can't use my FB & IG app on it. It needs to be updated. 😟
iPhone 3GS, iOS 4.1
