does anyone have a nokia 7390 and is it unlocked?

I have this phone which is locked to the 3 network but I want to have it unlocked so I can use Orange. I have taken it to a couple of places in town but they told me they didn't have the software to unlock it.
Has anyone any suggestions on unlocking this phone or how to do it.
Many thanks

Dont know if this helps but i had my daughters lg viewty unlocked, our local market stall said they didnt have the software as its a new phone and advised me to ring t mobile who it was locked too. I rang them and explained that I wanted to swop between t mobile and o2 and i paid £15 and got a long number which unlocked it. I had to wait 3 months from the first top up before they would issue it to me but once id got it they talked me through how to do it and it worked.
