IF you go for O2 online for £25 quid a month you can get 100 crossnet minutes, 500 texts or 125 media messages and 500 minutes of wap. and there is a few phones you get for free.
I don't think it's the best phone for polyphonic ring tones and I find that anything crunchy tends to sound a bit gay when it's given the polyphonic treatment anyway. 'Fraid I've stuck to one of the pre-loaded ones.
Let us know if you find anything half sensible though.
I got a t610 from Orange last week for free..they wanted £59.99
I told them I would leave orange and go to O2 and the retentions dept gave me the phone for free £22 for 100 x network minutes and 3 months free WAP
