Yes, we’re currently in the process of acquiring these samples. What samples? First up, there’s the ‘RedBrowser’ malware. Then there’s this one from mobileav.org, and i quote:

The Mobile Malware Researchers Association (MARA) today announced that it has characterized the first malware to cross-infect a handheld phone or PDA from a binary on the desktop PC. The malware, a Trojan dubbed “crossover”, spreads from a Win32 desktop machine to a Windows Mobile Pocket PC handheld.
