Thought these were good deals if you dont mind an old phone too much...
On 24 month contracts with 3 month free. Phone plans from $19
Xperia Ray, HTC Desire and Galaxy S are on $19 pm
Vodafone have this phone free on the $29 cap but they are offering a $20 per month discount on the $49 cap over 24 months. So basically getting the phone on the $49 cap for the price of the $29 cap.
