mobile phone

i'm in the market for a new mobile phone. i'm looking for something not too complicated or expensive, but still fun to play around with. an mp3 player on the phone would be nice. but basically i just want something that i can use for calls and SMS. XD

i'm looking at these three models:

Nokia 3110 Classic - i'm actually sick and tired of nokia (been using a toshiba vodafone for the past 2 years), but i saw this phone from a friend and it looks feature-packed for a good price. looks durable too.

Sony Ericsson W350 - this looks reeeeaaaally nice and i like the features. and it's not nokia. but it looks a bit fragile. browsing through the user feedback, a lot of people keep saying the flap (?) easily breaks.

Sony Ericsson K330 - this looks much more durable than the one above. AND it's not nokia (this is somewhat important to me, lol). but i'm not too sure about the features.

all these models cost around php5000 only.

feedback? any other recommendations aside from the ones listed? ^^
