How much would it cost to unlock Samsung Galaxy S2 which is locked on Vodafone network in a legit way like from the phone shop?

any estimates? is there anyway to do it for free?

Thanks

£20 from vodafone.

Vodafone will charge you about £15. If you want to do it legit then you wont get it free.

Quite expansive from shops so best is to look up on ebay/amazon

check online for unlock codes. search on google

you can do it urself i guess

but if you are on vodafone contract they will do for free just give it a try

thanks for replying so quickly

i had a iphone done for 15 quid from o2 so is the cost similar for Galaxy S2 from Vodafone? 

if i do it for free like this http://www.youtube.com/watch?v=STRSh7CbTGI&feature=player_embedded will it have any adverse effect on my phone?
