I have a Sony Ericsson w810i.

These are not a smartphone (i have a PDA for that) but as a phone they function very well with some nice extra touches.

its main selling point is the Walkman branded MP3 player function - not bad, only problem it lacks is the way it sorts track orders.

also consider the nokia 6820, these are popular phones at the moment, also the N80 and and the N91 (these are a much bigger than they look in a picture but 4GB built in memory )
