simox - Thanks for your answer. I may as well flash to the new firmware version, unless there is not a good reason to do so? I have:

K800_R8BA024_MAIN_GENERIC_WI_RED52
K800_R8BA024_FS_EUROPE_2_RED52

... which I believe is correct for the UK. After this I will have a little go with your tool and see what is what! It's quite interesting to go back into the world of SE. Makes a change from my current messing about with my new Nokia N82 and Asus Eee PC. Too many toys, I don't know what to do :) !!!!!
