Why pay for cheesy ringtones when you can make them yourself? Myxer website lets you load up your own audio (mp3) from a PC then sends it to whichever mobile number you've specifed. You can make customised wallpapers too
I received an SMS with a download link. The originating url was csoft.co.uk but it all works just fine with Aussie phone numbers (use +61xx format).
Sadly, my Nokia 5110 is too old for downloadable ringtones…happy Christmas.
Seems to be an american site?, I havent tried it thou. I assume you would still have to pay WAP fees to get it onto your phone, that adds up quickly, may aswell upload the file to freewebs.com and navigate to the address on your phone, probably cheaper to get a cable and connect your phone to your computer if you intend to add alot of songs.
