How To Unlock An iPhone
There are 2 reasons to unlock your iPhone that I’m aware of.
- To be able to use your iPhone on T-Mobile or another GSM network. (No, you can’t take it to Verizon!)
- To sell it. People like them more when they are unlocked.
How to Unlock It
First, you must have a jailbroken phone. See my [cref how-to-jailbreak-an-iphone] article. Then, check out this great instruction page on iClarified, whom I highly recommend for instructions on jailbreaking your phone as well. Simple as can be.
