Phone haylp?

[Brendocon]

Right, so I've got this swish little Samsung D500 thing. And it's all neat and stuff, apart from the space key being in the wrong place and the raised edge of the keypad tray getting in the way whenever I try and type, but it's nifty and takes pictures, plays music, has bluetooth... you know, all that modern shizzle that the kids are down with these days.

Now, I bluetoothed some mp3s from my PC to the phone (god bless technology, eh?), but can't for the life of me work out how to set one of them as my message alert. I'm sure it must be possible because... well, because the default set are rubbish and I'm sure no self-respecting phone manufactuer would intentionally limit me to that selection.

So, does anybody with any experience with this model know what the hell I'm meant to do to make my phone go "grrr argh" whenever somebody texts me?
