SEX X10 anyone? The Xperia X10 mini can be had from SmarTone-Vodafone for $0 – as long as you sign a contract of $298/month. However, it’s running on a somewhat outdated version of Android – version 1.6. It weighs in at only 88g and comes with a 5MP auto-focus camera with LED flash. Full X10 specs can be found here.
