What happens when you take a multi award-winning smartphone like HTC Desire and improve it? You end up with HTC Desire S, showcasing a spacious 3.7-inch screen, a stronger and slimmer unibody design, with a heightened sense of intelligence, speed and clarity. It's reliability on a whole new level.

Obviously not everyone will want it on 3, but it can be unlocked.
A quick search shows it can be unlocked for £12.99 here:http://www.mobileunlocked.com/HTC/Desire_S
There may be others cheaper if you look hard enough? I can't vouch for the company either... ;-)
If you are looking to unlock, it can be done for free here -http://forum.xda-developers.com/showthread.php?t=943726
