I purchased one of these for the missus and it appears that they have an issue with using .AMR format files as a ringtone. On my other handset (an office Nokia 6021) I have a particular ringtone that works fine. I transferred this to the 8800 via Bluetooth. When playing back the file via the Gallery menu, it's fine. The file plays through once from start to finish and sounds fine. However, when you set it as a ringtone, things go downhill rapidly. When it rings, it only gets part way through the file before it starts to repeat. So it plays half of the sound, then repeats. In short, it sounds like garbage. Has anybody else experienced anything similar? Seems pretty poor for a premium product, even if it has only recently hit the market.
