From the days of the oldest nokia communicators they could play arbitrary downloaded wavs. Something rare on phones od the day. I tended to copy ringtones from phone to phone as I upgraded. On the 9500 I liked the built in snapdragon.aac. Incdluding on the 9300 and copied it to the e90. But others started using it and so to tell my phone apart; I switched to Nuance.aac on my e90. I then found it didn't come on the N900 so I copied it from my N97* and still use it. Oh and the sms Message3.aac coped too.

* I had to write a quick python line to read it in from Z: and write to copyoffable memory as I didn't have a uk sim and so my wifi would't work on ch13. I only had python installed no 3rd party filemanagers!
