At £20 a month with a free handset, the HTC Wildfire is as good value as it gets. It's a bona fide smartphone running on the fun and easy to use Android 2.1, with a great capacitive touch-screen that supports multi-touch. You'll get apps, excellent internet features and as we note on page X, the best social networking around.
Business class email, BlackBerry Messenger and quality apps from the App World make the BlackBerry Pearl 3G one heck of a deal - though at £25 a month with a free phone, it doesn't quite manage to pip the Wildfire.
Love Android, but want your QWERTY keyboard too? The GW620 was one of the earlier Android phones, but it's still a capable little device with a five-line keyboard, full touch-screen and all the customisability of Android.
At just £30 on pay-as-you-go, you can't argue with the little INQ Chat 3G - and though it's no smartphone, it does push Twitter and Facebook onto the home screen, pack a comfy QWERTY keyboard and come with free Skype and Windows Live Messenger.
Samsung's Genio line was one of the year's most popular, and the Samsung Genio Slide one of its best, with a side-sliding QWERTY making texting and social networking eminently usable. HSDPA and Wi-Fi are a nice surprise in a handset this cheap.
