The risk with trying to unlock a newly released updated iphone firmware is that the jailbreak process can be risky simply because of the fact that not many iphone users have had the chance to unlock iphone 4 5.1. The challenge therefore becomes finding an actual working iphone 4 5.1 unlock solution that doesn’t have any risk of bricking iphones. That sounds easy doesn’t it? Unfortunately, there are too many “opportunity seekers” that claim to unlock iphones with iOS 5.1 firmware version and unfortunately they simply cannot.

Jailbreaking iPhone 4 is required in order to unlock it. Alot of people confuse the two operations and think that unlocking an iphone 4 is the same thing as jailbreak it. A jailbroken iPhone 4 is specifically what allows a user to install third party apps such as Cydia.
- How To Unlock iPhone 4 5.1: When you unlock iphones, you are basically telling the sim card that its okay to connect to a different cellular network than the one it was programmed for from the factory. A locked GSM sim card is intended to only connect to AT&T, Verizon, Spring, Orange, etc. By doing the unlock process, you are unlocking sim cards so that they have no bias when connecting to network providers. This alone has so many benefits and it’s why iphone 4 unlocking software is so popular on iphone unlock forums.
