From Wednesday, $79 but includes $10 sim and 50mb data. Seems decent specs for the price, shame about only 1gb ram but at this price can't complain. It's locked to Telstra, just not sure how is easy is to unlock.

Vodafone Mario Y550 would provide a better user experience, you get a 64bit Snapdragon quad core proccessor that really hauls ass, a slightly bigger display (4.5"), Kit Kat 4.4 and 4G LTE connectivity.. costs less too and is easily unlocked for 3-5 dollars.
