Sim-lock individual complex problem! Please help!

Hi all!
I'm a beginner in this forum so sorry if i start new thread, and sorry for my english!
I've got a big individual problem!
I've got an iphone 4s (Orange UK) with ios 7.0.3.. I live in hungary, and i use it with Gevey sim on Vodafone carrier (http://www.gevey.com/)
It was ok, but i do restore by chance.. and i get this message:
"There is no SIM card installed in the iPhone you are attempting to activate."
But i haven't got an Orange Uk sim-card, so i can't activate my iphone..
So what can i do? I try to obtain an appropriate, or wait for ios7 official jailbreak to use my phone? Or there is an other way for me?
Can i unlock it from IMEI in the internet? not so expensive?
please HELP! I'm helpless!
