Not sure how many teens and younger are after some horribly expensive smartphone, but while buying something today in Asda Living I saw the T-Mobile Vibe which is a touch screen phone with camera (2 Mpixel), MP3 player and FM radio.
Comes with a 2 GB microSD card already installed (it is ready to use, once it has been charged). As it is on T-Mobile it can also take Virgin Mobile SIM cards, or you might find some shop to unlock it.
I found the FM radio to be one of the most sensitive around (and is the first thing I test).
Phone has multiple alarms (I counted 5), stopwatch, organiser, calculator, world clock (and main display can be set to show time in two places, or just local time).
Contacts list can have photos included, so when someone phones it will flash up their photo (still experimenting to see best photo size that the phone can display).
