hey people,
well i flashed my phone to latest global firmware, then i lost all the pre-loaded software like pictures and ringtones etc..
so then i flashed back to the latest UK firmware, and i now have the sim card unrecognised problem.

any ideas?
I dont want to go back to the global firmware, cus i quite like the themes and images that are pre loaded.! ..

EDIT: installed all the firmware updates, latest was 92.7mb, and now everything is working, and even better than before. phew!! good luck everyone.
