Except my friend has that ringtone on his 5800XM and he has had it for MONTHS. So your logic I am afraid is incorrect, some people just can't be bothered to change it or find the default is louder than anything they can find to replace it with. The reason he has it I think is because he has been updating the firmware lately so it keeps defaulting.

For the record, I have no changes on my account but my credit check seemed to have been different to everyone elses. I ordered 24th September on T-Mobile Combi20 and MPD did a temporary hold on £90.98 (the total amount I pay up front for the phone plus p&p) for 48 hours.

Like Evad I did also provide my existing T-Mobile number, which I think they may have used for T-Mobile to confirm my credit without a credit check (T-Mobile customer support said I am pre-authed for up to 5 lines with them). This makes sense then that MPD did their own check just to make sure I could afford the phone. Although personally I think making sure you have enough money NOW in your account, weeks/months before you are expecting to need it, is plain stupid.
