Having managed to get a very early upgrade for a IP4 (I know) from those nice people at Orange I am now going to sell my Samsung 8910. I was going to put in a auction site but I have no idea how much its worth ? Its in pristine condition and locked to Orange. Does anyone know what sort of price I should be looking for ?

probably about £100 ... being locked will reduce the price.

I agree.
To be honest, because of which phone it is and the fact its on Orange, it might be better to use a phone recycling website.

Thanks for the replies. Just sold for about £150.00 on a auction site so very happy.
