Hi, where or how can I download the IOS 4.3 Updates on the Iphone 4?
The only way to update the iOS of a phone that is older than iOS 5.0 is to plug it into the computer and update through itunes
From iTunes on a computer.
The only version you can install on your iPhone 4 is 6.0.1. You cannot install an older version than the current one.
how to make an iphone 4 version 4.3 to 6.1 in itself?
If you currently have a version below 5 the only way to update it is by using iTunes. The over-the-air update feature was added in version 5.
