ok i dont know a lot about all this unlocking stuff so i have a couple of questions (i did read the board a bit before asknig)

1- i have a virgin phone, which has credit on so if i unlocked it could i still keep this credit

2- if i unlocked it and changed the network could i now use SMSC Numbers, on say o2

3- what kind of data cable do i need to do this or is it eaiser to pay someone to do it

sorry i am sure that theses questions have been asked beford but i couldnt see them

thanks for any help
