It's ok i have sorted it now,But there is one thing that didnt work.

I flashed the phone fine and used the vodafone cust pack because it was on voda before,then the person that owns it wants to change to 3 network, so i tried just flashing the 3 cust pack on its own without flashing the Main and FS again and it didn't work?

Do you have to flash all three again for it to work?

Just kept returning litle err messages when trying to ad the custom files at the end part of the cust flashing operation.

Thanks everyone for your help and patience.

changing firmware is not that easy, you need to flash '3' MAIN, FS and custpack

I sort of got round it,even though vodafone don't simlock there phones,i sim-unlocked it any way with aerix then flashed just the 3 cust pack, which changed all the correct settings for My3 and the web etc but left the voda startup splash and the vodalive gif image on the desktop left softkey, but that doesn't bother them so sorted it.

Once again i thank everyone for there help and this great site.
