Do you have to Unlock your iPhone 4 to Jailbreak it?

I'm experience with jailbreak as I have done multiple times on my Ipod touch 4g. I'm getting the iPhone 4 from a relative soon and was wondering if I needed to unlock the phone to jailbreak it?

Nope, just treat it like you would have with an ipod touch

No you need not unlock an iPhone to jailbreak it.

You don't need to unlock the phone to jailbreak it, you've to jailbreak the phone to unlock it.

No you need jailbreak to unlock it.

Jailbreaking will not Unlock the I-phone 4… Jailbreak and Unlock are different concepts… You can jailbreak the i-phone easily using the Site http://jailbreakiphone4i.com/ jailbreak removes the Restriction and makes the I-phone 4 to accept third party applications, music, software etc… Unlocking remobes the Network lock and makes the i-phone 4 to accept any country GSM Network sim card and work with that… You can visit the site http://www.simpleunlocking.com/apple-iphone-4/rs16wp9/ get remote unlock service and unlock it easily. Then use with any GSM Network sim card in it… In this method jailbreaking is not compulsory…
