The first real mobile tojans

It was predicatble that after it was shown possible malicious software for mobiles would start to show up. Well it has, first for Windows Pocket PC, then a few days later for Symbian. The Symbian one is obviously more dangerous as the operating system is much more wide spread, however this is interesting that it appeared after the Windows trojan as the much greater market penertration makes symbian a much better target.
