hi guys, yesterday I downloaded the pwnage tool 2.1 to jailbreak and apparently it said it would also unlock it (which I really want to do it as soon as possible) everything went smoothly , my iphone is jailbreaked and everything...but then I tried my 2 sim cards, one from portugal vodafone and the other one from orange uk, the iphone accepted both which I though was too good to be true but then I realised that I have no network service with any of my sim card not even from the original operator that was vodafone portugal. what shall I do?

I tried to use the quickpwn as I saw in a forum but it didn't helped ...I am a bit stressed about it and I really want my iphone unlocked because I can't use it if I don't unlock it...oh well. thanks for your time and patience to read my message and hopefully someone will be able to help me.
by the way I have got an iphone 3G 16GB
