Can anyone help me with my sony ericsson W810i

[dusty2508]

I have a sony ericsson W810i that I put into a local corner shop that unlocks mobiles, I paid £20 to have unlocked to any network.... I picked up the mobile and the dude said that it was unlocked, the original network was vodafone, I got the phone home, put in the orange sim card and the message said "insert correct sim". So I inserted the original vodafone sim card, and guess what? The same message came up, I have tried everyone that I knows sim and it still displays the same message, when you turn the power on it gives you the option to start phone or music only, I can access the music fine, but everytime I start phone it tells me to "Insert correct sim" can anyone please help me with this problem.....many thanks:confused:
