Updated Jailbreak and Unlock Programs Are Foolproof
You can easily unlock your iPhone on your own with downloadable programs. The software only works on jailbroken units, though, and you’ll also need Cydia to run the program. It’s fortunate that jailbreak and unlock programs are easily accessed and executed; you can even run these programs back to back on your iPhone. If you’re worried that your unit will brick with a misstep in the process, then you’re probably dwelling in the risks of first-generation jailbreaks and unlocks. The most recent updates are foolproof, and even if your unit becomes unresponsive halfway through the installation, you can still restore it to the default configurations at iTunes. You can safely start over in case you encounter glitches.
