I just installed an app for Android (Also available for iPhone, iPad and iPod touch) called eSnakes of South Africa.
It may be a little pricy but worth it I think for noobs like me wanting information and for identifying snakes. It's got some cool features. Very handy out in the bush!
Here's a link for more info and some screenies: https://play.google.com/store/apps/details?id=com.coolideas.eproducts.esnakes
