Can you still unlock an iphone5 if it's jailbroken?

I jailbroke my iphone5c about a month ago and I was wondering if you can still take it to a shop and jailbreak it? Thought I'd ask here before I go and do it. I live in scotland and my phone is locked to vodaphone

Yes even if its jailbroken you can still unlock it. But unlocking it will make it do a factory restore meaning you will have to re-jailbreak it again.
