F-secure is reporting that there is a new symbian trojan, called Skulls Trojan, which replaces all system applications with non-functional versions thereby disabling phone functionality. Icons will appear as the image on your left. To avoid it, do not install the Extended Theme Manager" by "Tee-222."
Their recommended fix is to use their product, and this seems like the best bet. If, however, you do not have web access from your phone, you cannot connect your phone to a computer, and the information on your phone is not vital, you can probably get away with reformatting it.
I wonder how long it takes before the number of Symbian trojans/viruses overtakes the number of Macintosh viruses; and if that is a good or bad thing...
