Hi,
If you are after a cheap good looking android phone(yes, cheap and good looking!), then look no further! Kmart is having the Sony Xperia E on sale for $59. It is network locked (Boost/Telstra). I emailed Bagman and he quoted $19 to unlock it, not sure if you can find it cheaper elsewhere.
Edit: You can find bagman's contact details here: http://www.ozbargain.com.au/node/91771
