The newer ones are noticeably quieter than the old ones. I had to switch to the MS ones so I could pick them out.
By the way, does anyone know how I pick between the Nokia and MS sounds for calendar alerts? Ta.
It doesn't help that the Amber update (at least in the EU) enforced a new, lower volume level (for me it's 13/30) every time you restart the device.
Now that we can set custom SMS tones, does anyone have an MP3 of the old tone?
