Dick Smith - $555 Sony Xperia S 32GB Unlocked Mobile + FREE Sony Headphones (+3% Cashback)
It doesnt say on the purchase page about the free headphones, but it is in the flash on the homepage. I have taken the picture and will post it at the bottom of this post.
The FREE Sony MXR-ZX300 headphones are selling at Oo.com.au for $39.99 + shipping
My guess is, this is a good price. Pros:
1) Comes with a FREE Sony MXR-ZX300 Headphones ($40+ value)
2) Dick Smith is easier to deal with warranty wise!
3) Aussie stock
4) + Buckscoop 3% cashback ;D (around $15)
Unique mobile has this phone for $579
Mobicity has it for $669
