How to unlock iPhone 4.2.1 – Risks and rewards
Before you proceed to know how to unlock iPhone 4.2.1, you should understand what you are signing up for.

So, naturally, the company is against unlocking the device. If you end up bricking your iPhone during unlocking, you should take necessary measures on your own to keep your phone working. The quality of service signal and battery life hugely depend on the unlocking method you use and if you end up using a wrong method for unlocking, you may not get all the benefits.
