HTC Desire S

The HTC Desire S is a slick, compact and attractive handset that's an improvement on its predecessor with more compact lines and an improved Sense experience - which has now been updated to the Sensation-matching Sense 3.5 offering.
It may only have a 5MP camera, but it's got a budget-busting price tag these days, so that means it's still going to have a decent customer uptake even with the might of the Android 4.0-powered One Series.
