If you need a really cheap phone Coles and Bi-Lo are offering the Samsung E1170 for $19 a saving of $20 or 51% off. I use cheap phones for things like mountain biking so that when, not if, I stack I don't destroy my iphone.

Samsung GT-E1170 What's in the box and a Short Look
tried to find a youtube video review for the Samsung GT-E1170 but none seem to be in English or are really terrible videos

This is a short review for Samsung GT E1170.
Sorry for the poor quality.
It's a very nice phone, if you want something cheap and basic that has a very good battery life.

If you have a review I'm interested to hear it, as may make a good back up phone!
