Just came across this, as I have a Smartphone (actually, everyone at my company does) I'm going to give it a try. We use Avira as our main AV engine here at the office and using the same supplier on the phones would be great.

After reading the reviews I'm a bit hesitant, though. It seems to be still really beta.. Reportedly not even working on Android 3 and we'll be getting Ice Cream Sandwich on all our phones I a couple of months. Doesn't hurt to try though!
