I've changed the voting poll (you forgot to put your question there
).
Yes, I think there definitely be viruses for smart mobile phones connected to the internet. And we can have two basic schemes (and of course many between them).
1) the OS, applications and Internet connection will be well designed and implemented. The viruses will be a very interesting piece of code as a proof of concept that they can exist but they will not mean the real danger
2) the software producers will not learn their lessons from our current OS/application situation. The viruses will be the biggest nightmare due to which many cell phone networks may collapse...
Your bets
