[Knoxville]

Well my o2 contract is coming to an end and I have no real deisre to change to another network and they've offered me wither £100 credit on my next bill (I never use anywhere near that much in a month) or a choice out of four new handset's -

Nokia 6230i
Sony Ericsson Z520i
Motorola L7 SLVR
Samsung S400i

I don't keep up with mobile phones much these days so I was hoping you guys could help me out, my current phones a Nokia 6230 and to be fair its done damn near everything I've asked it to but a camera with a zoom and more eliable battery life would've been nicer.

Basically whichever phone I choose has got to be -

Simple as hell to use (I still use the old school scrolling style menu's tbh)
Have awe inspiring battery life (its gotta go to festivals and amsterdam this year)
A camera (with zoom preferably)
MP3 and Video playback would also be a bonus

and generally be durable and able to survive in my pocket.
